Transformation of a pentagon


How to use the applet.

Drag each vertex of the pentagon (red points).
The applet below uses the fact that two triangles have the same area if they have the same base and the same height. You can change the shape of the pentagon, but the area is unchanged during the transformation. Make various shapes as you like.
