Besteman Construction II

The applet illustrates an algorithm for dividing a segment in N equal parts found by a college student, Nathan Besteman, and reported in the recent issue of *Mathematics Teacher*.

The construction employs a well known property of angle bisectors in a triangle. In ΔACD, let DP be the angle bisector of angle D. Then

(1) | AP/PC = AD/CD |

It follows from (1) that if CD = N·AD, then
