Question

Select the correct answer from each drop-down menu. In the figure, line segment AB is parallel to line segment CD. The measure of angle C is degrees, and the measure of angles D is degrees.

Answer 1

40 and 75

Explanation:

Answer 2

∠C = 40°

∠D = 75°

Explanation:

AB ║ CD, so AD and BC are transversals. The angle pairs (A, D) and (B, C) are "alternate interior angles", hence congruent.

∠C = ∠B = 40°

∠D = ∠A = 75°
