Question

prove a pair of corresponding angles formed by a transversal of two line is congruent then the two lines are parallel​

Answer 1

Answer:

Euclid's Proposition 27 states that if a transversal intersects two lines so that alternate interior angles are congruent, then the lines are parallel. Second, if a transversal intersects two lines so that interior angles on the same side of the transversal are supplementary, then the lines are parallel.
