In the subjects of geometry and trigonometry, a linear pair of angles is any two adjacent angles formed together to add up to 180°, or π (pi) radians. This rule is also known as the linear pair ...

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.

Adjacent angles are one of the earliest and most important concepts to learn in basic geometry, as they have applications in further subjects like trigonometry, physics, and engineering. Effective ...
