Question

AD bar is a diameter of F. Find the following arc measures:

m cap BC = _____ m cap CD = ____ m cap AD = _____ m cap AB = ____ m cap AC = ____ m cap AEC = ____

Answer 1

Calculate the arc angles using geometry.

m cap BC = 90^O

m cap CD = 45^O

m cap AD = 180^O(Since straight line angle)

m cap AB =180-90-45= 45^O

m cap AC =90+45= 135^O

m cap AEC =180+45= 2255^O
