Question

problem 10: (first taught in lesson 17) complete this sentence by selecting always, sometimes, or never. if two angles are complementary, then the angles are __________ adjacent. after you pick your answer press go. a. always b. sometimes c. never

Explanation:

Step1: Define complementary angles

Complementary angles are two angles whose sum is 90 degrees.

Step2: Define adjacent angles

Adjacent angles share a common side and a common vertex.

Step3: Analyze the relationship

There are cases where complementary angles are adjacent (e.g., two angles in a right - angled triangle that are not the right angle). Also, there are cases where complementary angles are non - adjacent (e.g., two separate angles in different parts of a figure that add up to 90 degrees). So, if two angles are complementary, they are sometimes adjacent.

Answer:

B. sometimes
