Squaring a Convex Polygon
This applet constructs a triangle with an area equal to the area of any convex polygon ABCDEF. The applet Squaring a Triangle shows how any triangle can be transformed to a square with an equal area. The combination of these two constructions shows how to square any convex polygon.
- Click on point F.
- Drag F to the right as far as it can go.
- Repeat these two steps three times, until the triangle is constructed.

Circumcircle and Incircle of a Triangle
This GeoGebra worksheet below shows that in a triangle, you can always create an incircle (a circle inside the triangle tangent to the tree sides) and a circumcircle (circle passing through the three vertices).
