A) The stop sign is a regular octagon, so the measure of angle F must be 67.5°. What is the angle measure for angle L?

B) What is the measure of angle E? Explain how you know.

C) What is the measure of angle K?

D) What is the measure of angle H? Explain

A) ∠L = 67.5°

B) ∠E = 112.5°

C) ∠K = 112.5°

D) ∠H = 67.5°

Step-by-step explanation:

A) ∠L is alternate interior to ∠F so it is equal to 67.5°

B) ∠E is supplementary to ∠F so ∠E = 180° - 67.5° - 112.5°

C) ∠K is alternate exterior to ∠E so ∠K = 112.5°

D) ∠H is a vertical angle to ∠F so ∠H is 67.5°
