"The degree measure of the diameter and the degree measure of the semicircle are the same."

Reason: A semicircle is half a circle = 180°. A diameter forms a straight angle (180°) through the center. Their angle (degree) measures are both 180°. The lengths, however, are different (semicircle length = πr while diameter = 2r).
