An angle is the space between two lines that start at the same point. Angles are measured in degrees (°). They can measure between 0° and 360°. Different types of angles include acute, obtuse, reflex ...

In this video we will learn about the Complementary angles, Supplementary angles, Adjacent angles, Linear Pair, Vertically opposite angles and Proof for vertically opposite angles being equal.

Angle: The measure of the opening between two intersecting lines is called an angle. Unit: The unit of angle is radians or degrees. Angle formula: There are different types of formulas for calculating ...
