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.

\(x\) is 50°. Corresponding angles are equal. \(y\) is 180° - 50° = 130°. Angles on a straight line add up to 180°.

A right angle is exactly 90°. It is shown by a small square. Angles that add together to make a right angle are called complementary angles. If you know one complementary angle you can subtract it ...
