Triangle Properties

Triangle Properties:

Vertex: The Vertex is a corner of the triangle. Every triangle has three vertices.

Base: The base of a triangle can be one and all of the three sides, usually the one drawn at the bottom. You can pick any side you like to be the base. Commonly used as a suggestion side for calculating the area of the triangle. In an isosceles triangle, the bottom is usually taken to be the unequal side.

Altitude: The altitude of a triangle is the at right angles from the base to the opposite vertex. (The base may need to be extended). Since there are three likely bases, there are also three likely altitudes. The three altitudes meet at a single point, called the orthocenter of the triangle. See Orthocenter of a Triangle.

Median: The median of a triangle is a line up from a vertex to the midpoint of the opposite side. The three medians meet at a single point, called the centroid of the triangle. See Centroid of a Triangle.

Area: See area of the triangle and Heron's formula.

Perimeter: The distance around the triangle. The sum of its sides. See Perimeter of a Triangle. This could also help us on fifth grade math

Interior angles: The three angles on the within of the triangles at each vertex. See Interior angles of a triangle

Exterior angles: The angle between a face of a triangle and the extension of an adjacent side. See Exterior angles of a triangle.

Area of a square formula

In this article let me help you on area of a square formula. Keep reading if you still have any doubts do leave your comments.
In algebra completing the square method is a framework to for converting a polynomial procedure of the contour ax^2 + bx + c to the mold (x +-k) ^2 + steady. We can also find the area of a square formula. But for now let’s start with completing square formula.

As for example here is a base representation:

Analyze the quadratic sum x^2 + 12x + 40

X^2 + 2. x. 6 + 40

The above multinomial amount is not a all paddle as 40 is not the number of 6

(x + 6)^2 = x^2 + 12x + 36. This could also help us on balancing chemical equations practice

Nevertheless, it is accomplish able to create the first quadratic as the sum of this shape and a steady:

X^2 + 12x + 40 = (x + 6)^2 + 4

logarithms rules

The rules of logarithms are as follows:
Lets study about logarithms rules.
Loga mn = loga m + logan, where ‘a’ is any positive number such that a≠1

Loga m/n= loga m - logan , and

Loga mb = b loga m

Where b is any rational number and m and n are positive number.You can apply the same rules on corresponding angles

Example Log15 = Log 5 + Log 3

Log 4/5= Log 4 – Log 5

Log64= Log 43 = 3 Log 4

Exercise1. convert into exponential form logm n = p

Options A. np = m

B. mp= n

C. pm= n

D mn=p

Note on Simplifying Fractions

Simplifying Fractions:
A numerical expressions representing a part of a larger whole number. A fraction numbers can be converted to a decimal by dividing the upper number, or numerator, by the lower number, or denominator.

We call the top number the Numerator.
We call the bottom number the Denominator.
Example 1: 12/64(simplifying Fractions)
The fraction 12/64 is not reduced to lowest terms.
We can simplify this fractions to lowest terms by dividing both the numerator and denominator by 4. This could also help us on mean maths
Why divide by 4? 4 is the Greatest Common Divisor (GCD)
or Greatest Common Factor (GCF) of the numbers 12 and 64.
So, this fraction reduced to lowest terms is3/16
The final answer is 3/16

Following introduction will help you better on this article after going through if you still have any problems or comments do leave your comments or even if you wish to share anything in specific let me know so that in the next article i can help you on that in particularly.

In thermodynamics we will be discussing two types of property

1 Extensive property
2. Intensive property

Extensive Property

The properties that depend on the mass or size of the system, more clearly on the amount of substance are called as extensive properties. Examples: volume, number of moles, mass, energy, internal energy etc. The value of the extensive property is equal to the sum of extensive properties of smaller parts into which the system is divided. Suppose x1 ml, x2 ml,x3 ml of 1,2,3 gases are mixed in a system, the total volume of the system equals to (x1 + x2 + x3) ml. Thus volume is an extensive property.This could also help us on logical reasoning test

Help on Percentage Formula

Today let me try to help you on one among the important formula in math that is percentage formula with out which math is incomplete.

The formula for percentage is the following and it should be easy to use:




We will take examples to illustrate.Let us start with the formula on the left

An important thing to remember: Cross multiply

It means to multiply the numerator of one fraction by the denominator of the other fraction. This could also help us on working out percentages

Example :

25 % of 200 is____

In this problem, of = 200, is = ?, and % = 25

We get:

is/200 = 25/100

Since is in an unknown, you can replace it by y to make the problem more familiar

y/200 = 25/100

Cross multiply to get y × 100 = 200 × 25

y × 100 = 5000

Divide 5000 by 100 to get y

Since 5000/100 = 50, y = 50

So, 25 % of 200 is 50

Introduction to Isosceles trapezoid

Introduction to Isosceles trapezoid:

In this section let me help you on isosceles trapezoid. Isosceles trapezoid is one of the type of quadrilateral with a line of symmetry bisecting one pair of opposite sides, make it automatically a trapezoid .Isosceles trapezoid a two-dimensional figure produced by relating four segments endpoint to endpoint with each segment intersecting exactly two others. Isosceles trapezoid also has four sides and four angles.

Sum of interior angle of any polygon is (n-2) *180o. Here isosceles trapezoid has four sides so interior angle is (4-2)*180o = 360o.Exterior angle of any polygon is 360o so the exterior angle of a quadrilateral is 360 degree. In this article we shall discuss about isosceles trapezoid.This could also help us on online fraction calculator.


The diagonals of an isosceles trapezoid are same. Diagonals divide each other into segments of the same length. The isosceles trapezoid PQRS has diagonals PR and QS have the same length (PR = QS).Intersect the diagonals at point O and diagonals are divide each other in segments of the same length (PO = SO and QO = RO).

Help on Conditional Probability

Conditional Probability

The conditional probability of an event B will be the probability that the event will occur given the knowledge that an event A has already occurred. This probability is written P(B|A), notation for the probability of B given A. In the case where events A and B are independent to the conditional probability of event B given event A is simply the probability of event B, that is P(B)..

Let us consider the events A and B are not independent, then the probability of the intersection of A and B (the probability that both events occur) is defined by

P(A and B) = P(A)P(B|A). This will also help us on how to calculate pi

From this definition, the conditional probability P(B|A) is easily obtained by dividing by P(A):

P(B|A)= P(A and B)/ P(A)

This expression is only valid when P(A) is greater than 0.

calculating probability

Calculating Probability concepts and probability theorems is an interesting topic to debate with. The word Probability is something which we use on day today conversation.

In everyday life, we come across statements such as
(1) It will probably rain today.
(2) I doubt that he will pass the test.
(3) Most probably, Kavita will stand first in the annual examination.
(4) Chances are high that the prices of diesel will go up.
(5) There is a 50-50 chance of India winning a toss in today’s match. This will also help us on how to calculate probability

The words ‘probably’, ‘doubt’, ‘most probably’, ‘chances’, etc., used in the statements above involve an element of uncertainty. For example, in (1), ‘probably rain’ will mean it may rain or may not rain today. We are predicting rain today based on our past experience when it rained under similar conditions.

What is Algebra?

What is Algebra?

Alg

ebra is the branch of mathematics concerning the study of the rules of operations and relations, and the constructions and concepts arising from them, including terms, polynomials, equations and algebraic structures. Together with geometry, analysis, topology, combinatorics, and number theory, algebra is one of the main branches of pure mathematics.

We Use Algebra Everyday?

Algebra is used everyday, all the time. It is used in problem solving situations

when you are trying to determine how long it will take you to get from your home to your friends house.

Algebra is much broader than elementary algebra and studies what happens when different rules of operations are used and when operations are devised for things other than numbers. Addition and multiplication can be generalized and their precise definitions lead to structures such as groups, rings and fields, studied in the area of mathematics called abstract algebra. sample algebra problem

Note on Regular and Irregular Polygons

-->

Polygons:

In this lesson let me help you go through on regular and irregular polygon.

A simple closed figure bounded by three or more lines segments is called a polygon.

The line segments forming a polygon are called its sides. Polygons are named according to number of sides they possess.

Regular Polygon:

A polygon having all sides equal and all angles equal is called a Regular Polygon.

Examples: (i) An equilateral triangle is a regular polygon of 3 sides.

(ii) A square is a regular polygon of 4 sides.

Properties of a Regular Polygon:

1. In a regular polygon all interior angles are equal

2. In a regular polygon all exterior angles are equal.

3. A circle can be circumscribed about every regular polygon.

A circle can be inscribed in every regular polygon.

Irregular Polygon:

A polygon that is not a regular polygon , that is a polygon whose sides are not all the same length or whose angles are not of the same measure is called an Irregular Polygon

Perimeter of an Irregular Polygon:

The sum of all the sides’ lengths is called its perimeter.

Area:

There is no easy formula for the area of an irregular figure, we convert an irregular polygon to simple polygons and find the individual areas and the sum of the individual areas gives the area of the irregular polygon.
