Question

which angles are complementary to each other? select all that apply. ∠1 and ∠6 ∠1 and ∠5 ∠6 and ∠4 ∠3 and ∠4

Explanation:

Step1: Recall definition of complementary angles

Complementary angles add up to 90 degrees.

Step2: Analyze angle - pairs

From the figure, we see that ∠3 is a right - angle (90 degrees). If two angles make up ∠3, they are complementary.

Step3: Check angle - pairs

∠3 and ∠4 together form a right - angle. So, ∠3+∠4 = 90 degrees.

Answer:

∠3 and ∠4
