WebAs Diameter is a line segment passing through the center and it has an angle of 180 degrees so the measure of the intercepted arc will be 180 degrees and then by the inscribed angle theorem that inscribed angle will be 90 degrees. because inscribed angle = intercepted arc / 2 so the inscribed angle would be 180/2 = 90 degree. • ( 14 votes) asmodeus WebBelow are the three theorems, which we will be used later on in this article to make some proofs: Theorem 1: Perpendicular when two lines intersect to form a pair of congruent angles. If two lines intersect to form a linear pair …
