Draw a line segment PQ = 8 centimeter. Construct a perpendicular bisector of the line segment PQ. Let the perpendicular bisector drawn meet PQ at point R. Measure the length of PR and QR. Is PR = QR?

In the figure (not to scale) AB = CD, angle DAP = angle DPA and A,B,C,D are concycli. If angle ADC = 80°, then find angle ACD.
