Question

1. what kind of angles are ∠3 and ∠7? corresponding angles complementary angles vertical angles same - side interior angles

Explanation:

Step1: Recall angle - pair definitions

Corresponding angles are in the same relative position at each intersection where a straight - line crosses two others. Complementary angles add up to 90 degrees. Vertical angles are opposite each other when two lines intersect. Same - side interior angles are between two lines and on the same side of a transversal.

Step2: Analyze the position of ∠3 and ∠7

∠3 and ∠7 are in the same relative position at the intersections of the transversal with the other two lines.

Answer:

Corresponding Angles
