# MATH TERMS STARTING WITH A

AAA similarity test :

This is one of the three ways to test that two triangles are similar. Two triangles are said to be similar if the measure of three interior angles in one triangle are the same as the corresponding angles in another.

Here ∠A and ∠R∠B and ∠Q∠C and ∠R are equal.

AAS congurence :

This is one of the way to test the congruency of the triangles. It states that, Two triangles are said to be congruent, if two adjacent angles, and a side of one triangle are congruent with the corresponding angles and side of the other triangle. Abacus :

Abacus is a counting tool used for early learners of math. It is also called as adding machine. It is a belief that this adding machine was used by early Aztecs in 300 BC. It is helping us in acquiring the ability to calculate accurately as well as rapidly.

It is helping us to improve our ability to calculate mentally in more efficient manner. It helps provides concrete understanding of counting such as addition, subtraction, multiplication and division. Absolute Value :

The absolute value of a number is its distance from 0 on a number line.

For example, the number 5 and -5 is 5 units away from zero. So its absolute value is 5 and -5 is 5.

|5| = 5  and |-5| = -5

Angle :

An angle is nothing but the figure which is formed by the two rays, which are called as the two sides of that particular angle. Those two rays would have a common end endpoint which is known as vertex of that particular angle.math terms startingwith a. Acute Angle :

The angle which is less than 90 degree is called Acute angle. 30°, 45° and 75°are some examples of acute angle. Alternate interior : <1 and <2 are alternate interior angles and <3 and <4 are alternate interior angles and they are equal.

Alternate exterior angles : <1 and <2 are alternate exterior angles and <3 and <4 are alternate exterior angles and they are equal.

Refers to a pair of angles, that share a common vertex and side did not overlap. When referring to polygons, two interior angles that share a common side are also called as adjacent angles. It can also be called as adjacent interior angles of the polygon. Altitude :

Height of an object above sea level.  Average Rate of Change :

The change in the value of a quantity divided by the elapsed time. For a function, this is the change in the y-value divided by the change in the x-value for two distinct points on the graph. Axis of symmetry :

The graph of a quadratic function is a parabola. The axis of symmetry of a parabola is a vertical line that divides the parabola into two congruent halves. The axis of symmetry always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola. Angle of Elevation :

The angle of elevation is an angle formed by the line of sight with the horizontal when the point being viewed is above the horizontal level. That is, the case when we raise our head to look at the object. Angle of depression :

The angle of depression is the angle between the horizontal line and the observation of the object from the horizontal line If the object observed by the observer is below the level of the observer, then the angle formed between the horizontal line and the observer's line of sight is called the angle of depression. Angle between two lines :

Angle lies between two lines is called angle between two lines.

θ = tan-1 |(m₁ - m₂)/(1 + m₁ m₂)| Arc length :

Arc length of a sector is the length of the portion on the circumference of the circle intercepted between the bounding radii and is denoted by l. Formula to find the length of the arc is

l  =  (θ/360°) x 2πr

In matrix adjoint refers to the transpose of co factor of the given matrix. It is denoted as adjA for a matrix A.

Algebra :

Algebra is a branch of math in which we use letters in the place of unknown values.

Algorithm :

Explains how to solve a problem step by step instructions. You can understand how to take square root for any number you can refer the page square root algorithm.

Alpha :

The first alphabet of ancient Greece which is used in math and science. Area :

Area is nothing but the quantity which exposes the extension of two dimensional surfaces. This is one of the most important sub topics.

Associative property :

Associative property deals with grouping of elements under any operation. In other words, if a, b and c are elements of set A, and * is the operation, then

a*(b*c) = (a*b)*c

In mathematics, the additive inverse of a number a is the number that, when added to a, yields zero. This number is also known as the opposite (number), sign change, and negation

Additive inverse of -5 is 5.

Arithmetic sequence :

A sequence is said to be an arithmetic sequence if the difference of each term, except the first one, from its preceding is always same.

Arithmetic series :

Arithmetic series is nothing but sum of arithmetic terms.

5 + 10 + 15 + 20 +.........

Arithmetic mean :

Arithmetic mean means the sum of the given data, divided by the total values of the set.

Asymptotes :

An asymptote to a curve is the tangent to the curve such that the point of contact is at infinity. Apart from the stuff given in this section, if you need any other stuff in math, please use our google custom search here. You can also visit the following web pages on different stuff in math.
