50 points. 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. 1. 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. 2. what is the measure of ∠e? explain how you know. 3. describe the relationship between ∠e and ∠k. what is the measure of ∠k? 4. what is the measure of ∠h? explain. 5. what is the measure of ∠i? explain. 6. describe the relationship between ∠h and ∠l.
