A Heart As Good As Any
- Dave Van Leeuwen
Basic geometry as work. Circles with radii 1, 3, and 6, centered at the origin at 3 units below. Two points rotating counterclockwise at the same rotational speed, one clockwise at twice that speed. Those points are connected to form a triangle, and two angle bisectors shown. The trace shows the path of the point of intersection of those medians, the incenter.
