Definition of Angle
An angle is nothing but a measure of the degree of rotation around a point, line, or plane. The two lines that are joined to form the angles are called “Arms of Angle” and the point where they meet is called Vetrex. The image added below shows parts of the angles,
Angle is either measured in degree or in radian.
Complementary and Supplementary Angles
Complementary and Supplementary Angles are the pairs of angles whose sum is 90° and 180° respectively.
Complementary angles are pairs of angles whose measures add up to 90 degrees. In other words, when you have two complementary angles, the sum of their measures equals a right angle.
Supplementary angles are nothing but when the sum of two angles is equal to the straight line angle or 180 degrees. Supplementary angles are frequently encountered in various geometric shapes, such as parallelograms and straight lines.
In this article, we will learn about, supplementary angles and complementary angles, how to find the complementary and supplementary angles, their differences, and some practice questions on the above. Let’s start by understanding the definition of angle and its types.
