This animation shows the straightedge and compass method of drawing the Tree of Life that comes closest to solving the problem of dividing a line into thirds and a circle into sevenths. It can also be used to derive a third, a fifth, and a sixth of a circle, as well as the ability to construct a ten and twelve-part measuring rod.
Try to make a measuring tool with twelve equal parts with only a straight edge and compass and see how close you can get.
How many different geometric shapes can you create by only using a straightedge and compass?
