(1) Extend A

(2) Use the homothety w.r. to the orthocenter H, mapping the Euler circle to the circumcircle and define the angle(MON) homothetic to anlge(PED). Compare angle(MON) and angle(CA

This property is used in the discussion (and animation) of all rectangular hyperbolas circumscribed on the triangle A
