Question

Refer to the figure below to complete the following. if the measurement of arc AB=120, then angle ADB=? m. of arc AD=? measurement of angle ACD=?

Answer 1

m arc AB = 120

so m < ADB = 1/2 (120) = 60 because the measure of an inscribed angle of a cirlce is 1/2 its intercepted arc.

m of arc AD = 60 because a semicircle has measure 180

m < ACD = (1/2) 60 = 30 because the measure of an incribed angle is (1/2) its intercepted arc.
