[br][br]Below, we have 2 squares with a common vertex. [br][br]You can move any of the [b]LARGE POINTS [/b]anywhere you'd like [b]AT ANY TIME[/b]. [br][br][b]Questions: [/b] [br][br]1) What is the measure of the (soon-to-appear) [b][color=#ff00ff]pink angle[/color][/b]? [br][br]2) How can we explain why the measure of the [b][color=#ff00ff]pink angle[/color][/b] at the end (with [b][color=#38761d]green vertex[/color][/b]) never changes? [br][br]
