Geometry Through Art

The following illustrations show a sequence of some of the possibilities resulting from inscribing diameters, arcs, and other chords.

Given: 2 points, A and B.

Construct point A as the center of a circle. Make point B on the circumference of a circle using a clear transparent plastic cover of any coffee can.

. . . .

Note that arcs must intersect both the center of the circle and its circumference.
