[br][br]The 2 LARGE POINTS are moveable.[br]The octagon shown here is regular. The green quadrilaterals are squares with equal areas. [br]Lines and segments that appear to be parallel ARE parallel. [br][br][color=#ff00ff][b]How can we formally prove what is dynamically illustrated here? [/b][/color]
