First prove an easier result. If P and R are a diameter, i.e. when the line segment joining the two points passes through the center.
We are given a circle centered at O, and points P, Q, and R on the circle. We want to prove the central angle POR is twice the measure of the inscribed angle PQR.
I do not know how to set up the steps for the proof!! Help, please if you can!
I do not have any way to create images and would like to know wirhout adding new programs'
Relative to the original problem a central angle equals the arc, the inscribed angle of the same arc is half the arc.The wording of the problem was confusing since it was not specifed thatQ was a point outside PR
I assumed a case where Q was the center of PR and then made an error in the answer. the inscribed angle should be 150 degrees
