Question

1. name the relationship between <a and <b (select 2) a) supplementary b) complementary c) adjacent d) vertical

Explanation:

Step1: Recall angle - relationship definitions

Adjacent angles share a common side and a common vertex. Complementary angles add up to 90 degrees. Supplementary angles add up to 180 degrees. Vertical angles are opposite each other when two lines intersect.

Step2: Analyze ∠a and ∠b

∠a and ∠b share a common side and a common vertex, so they are adjacent. Also, the right - angle symbol indicates that ∠a+∠b = 90°, so they are complementary.

Answer:

b) complementary, c) adjacent
