Given four concyclic points (lie on
the same circumference) A,B,C,D, if four circles through AB,
BC, CD, and AD are drawn, prove that the remaining four intersections points
A', B', C', and D' of successive circles are concyclic.

Geometry Designer is an exciting app that allows you to draw traditional geometric figures that you might see in a high school or college math class.
You can draw points, lines, line segments, rays, circles, arcs, and polygons. For constructions you can make angle bisectors, intersections, midpoints, and perpendicular lines. You can take measurements of angles, lengths, areas, circumferences, arc lengths, and distances.
