Question

State and prove the property of corresponding angle test for parallel line.​

Answer 1

Proof: => Assume L and M are parallel, prove corresponding angles are equal. ... Note that β and γ are also supplementary, since they form interior angles of parallel lines on the same side of the transversal T (from Same Side Interior Angles Theorem). Therefore, since γ = 180 - α = 180 - β, we know that α = β
