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.

b) what is the measure of e? explain how you know.

c) describe the relationship between e and k. what is the measure of k ?

d) what is the measure of h?

e) what is the measure of i ?

f) describe the relationship between h and l.
