Geometry Ch14.2 #22 #23

Question from John:

Please explain the answer given in the Enhanced Teacher’s Guide for Chapter 14, Lesson 2, Number 22, 23.

Answer from Dr. Callahan:

The method implied in Jacob’s Enhanced Teacher’s Guide is based on dividing the polygon into triangles by drawing diagonals from one vertex. This is illustrated by exercises #38-51 of Chapter 7, Lesson 1 (pages 262-263).
