The degree measure of the diameter and the degree measure of the semicircle are the same.
Step-by-step explanation:
Diameter is the chord passing through the centre of the circle. It is the longest of all the chords of a circle. Semicircle refers to half circle. It is to be noted that semicircle has its base on the circle's diameter.
As we know that the angle measure of the diameter is 180 degrees (since diameter is also a straight line whose angle equals 180 degrees )
Similarly, the degree measure of the semicircle is half of the complete circle i.e. 360/2= 180 degrees.
Thus, angle subtended by the diameter is same as that of the angle made by the semicircle.
