Step 3: Two parallel lines cut by a transversal For our safety, it is important that drivers recognize a stop sign immediately. Stop signs are made with exact side and angle measurements to form a regular octagon. They are red so they are easy to see. The three lines drawn below are straight lines. Lines a and b are parallel.

a) The stop sign is a regular octagon, so the measure of ∠F must be 67.5°. What is the angle measure for ∠L? Describe the relationship between ∠F and ∠L. (1 point)

b) What is the measure of ∠E? Explain how you know. (1 point)

c) Describe the relationship between ∠E and ∠K. What is the measure of ∠K? (1 point)

d) What is the measure of ∠H? Explain. (1 point)

e) What is the measure of ∠I? Explain. (1 point)

f) Describe the relationship between ∠H and ∠L. (1 point)
