Congruent. Exactly equal in size and shape. Congruent sides or segments have the exact same length. Congruent angles have the exact same measure. For any set of congruent geometric figures, corresponding sides, angles, faces, etc. are congruent. Note: Congruent segments, sides, and angles are often marked.
If two parallel lines are cut by a transversal, then the pairs of corresponding angles are always congruent.Postulates are not proved, but are assumed to be self-evident and true. So pairs of angles which lie on the same side of transversal and the same side of both parallel lines are congruent.
