Question 0

What is an implication of the protractor postulate?

Answer 0

If ray OC is paired with x and ray OD is paired with y, then the measure of angle COD equals the absolute value of x-y

Question 1

What does the protractor postulate say?

Answer 1

If rays OA and OB are opposite rays, then rays OA, OB, and all overhear rays with endpoint O that can be drawn on one side of line AB can be paired with real numbers from 0-180
Ray OA will be paired with 0 and ray OB will be paired with 180
