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.
Parallel lines are straight lines which have the same direction and so never meet. Arrowheads show lines are parallel. A straight line that cuts a pair of parallel lines is called an intersecting ...
\(x\) is 50°. Corresponding angles are equal. \(y\) is 180° - 50° = 130°. Angles on a straight line add up to 180°.
