| Description |
English: A diagram showing Johnson's theorem. If three circles of radius r (blue) intersect at H, the circle drawn through the other three intersections (the circumcircle, red, of ΔABC, black) also has radius r. The Johnson triangle of ΔABC is then the triangle drawn between the three centres of the circles (green). The circumcircle of the Johnson triangle (orange) also has radius r. |
