What angle pairs are congruent: A) Corresponding B) alternate interior C) alternate exterior D) same side interior
A) Corresponding angles are congruent when two parallel lines are cut by a transversal. Corresponding angles are the angles that are in the same position (i.e., same relative location) on each of the two intersecting lines.
B) Alternate interior angles are congruent when two parallel lines are cut by a transversal. Alternate interior angles are the angles that are on opposite sides of the transversal and inside the two intersecting lines.
C) Alternate exterior angles are congruent when two parallel lines are cut by a transversal. Alternate exterior angles are the angles that are on opposite sides of the transversal and outside the two intersecting lines.
D) Same side interior angles are supplementary, not congruent. Same side interior angles are the angles that are on the same side of the transversal and inside the two intersecting lines.
