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.

Angles that add together to make a straight line are called supplementary angles. If you know one supplementary angle you can subtract it from 180° to find a missing angle.

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