Triangle Paradox (Missing square puzzle)
The two shapes have the same area. So where did the black square come from then?
Sum of the exterior angles of a convex polygon.
On the screen, we can see a regular polygon and we can change the number of its sides by using the slide bar. An exterior angle is also mentioned, as this is a regular polygon all exterior angles will remain equal. Let us change the value of n and move the points A &B and observe how the shape and size of the polygon gets changed.
1. In all conditions what is the sum of the exterior angles?[br]2. Is there a relation between sum of the exterior angles and the number of sides?
