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 are often described using three letters. Angles can be drawn and measured using a protractor. Finding angles between lines Complementary angles form a right angle. Supplementary angles form a ...

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