Since inscribed angles are half the measure of their intercepted arc, angle CAB is equal to 1/2(60 degrees), which is 30 degrees. ideo: Inscribed Angle and Arc Relationship ideo: Circles: Inscribed Angles and Arcs Instructional Videos View this instructional video. ideo: Inscribed Angle ...
Given the intercepted arc or central angle, to find the inscribed angle, divide the measure by two. This is the value of the inscribed angle. What is the formula for the inscribed angle? Consider an inscribed angle measuring x and the corresponding central angle or intercepted arc of measure...
