👉 Learn how to find the value of an unknown variable in the expressions representing the values of angles given the ...

👉 Learn how to define and classify different angles based on their characteristics and relationships are given a diagram.

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 ...

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°.
