Question

check all relationships between ∠1 and ∠2. options: adjacent angles, supplementary angles, congruent angles, complementary angles, linear pair angles, vertical angles. diagram with ∠1, ∠2, and a right - angle structure.

Explanation:

∠1 and ∠2 share a common vertex and side (adjacent) and their sum is 90° (complementary). Vertical angles are opposite, linear pairs sum to 180°, supplementary sum to 180°, and congruent angles are equal (not indicated here).

Answer:

Adjacent Angles, Complementary Angles
