In Class:
Construct orthogonal circles from 3 points and/or circles. Add a point at infinity to form the inversive plane and its i-points and i-circles. Theorem: The inversion image of a line is a line (i.e., the inversion image of an i-circle through infinity is an i-circle through the center of the mirror circle).
