PLEASE SEE the ATTACHED IMAGE TO SEE QUESTION AND FIGURE. Previous problem says the following (may or may not be helpful): Given a circle with center O and a point A ≠ O inside the circle, we construct the line perpendicular to OA at A and denote by X one of the intersections of that line with the circle. The tangent line to the circle at X then intersects OA at point C. We let Q be the midpoint of AC. Last edited by skipjack; May 16th, 2017 at 06:15 AM.
