Question

which angles are complementary to each other? ∠6 and ∠1 ∠4 and ∠1 ∠5 and ∠3 ∠5 and ∠4

Explanation:

Step1: Recall complementary - angle definition

Two angles are complementary if their sum is 90°.

Step2: Analyze each option

• For ∠6 and ∠1: There is no indication that ∠6+∠1 = 90°.
• For ∠4 and ∠1: There is no indication that ∠4 + ∠1=90°.
• For ∠5 and ∠3: Since the angle marked with a right - angle symbol is composed of ∠5 and ∠3, ∠5+∠3 = 90°.
• For ∠5 and ∠4: There is no indication that ∠5+∠4 = 90°.

Answer:

∠5 and ∠3
