 Question 1956: Question: Find the measeurement of angle APC Known Line AP has a point B on it Line PC has a point D on it Lines AB and CD are the same length Lines AB and CD are both Chords of a circle The measurement of Arc ACD is 200 degrees Point P is outside the circle Is there enough information to determine the measeurement of angle APC? Answer by longjonsilver(155): please explain what "measurement of arc acd = 200 degrees" means since an arc will have a length, not an angle, so which angle do you mean? Jon Let me restate the problem as it was originally presented. The notes above are my interpertation of the problem. Hope this helps. A circle with two secants that have a common end point that is outside of the circle. the end point is named p, the top secant is abp and the bottom secant is named cdp, ab and cd are congruent, the measurment of acd is 200 dedrees, so is cab.
