Got your attention. Didn’t it? Thought it might with such a group. Besides all the general and special reasons; I miss her because she was a geometry teacher.
Been thinking more about applied geometry lately. Seems fitting when dealing with shapes. Here’s a curious thought. The sum of the interior angles of a polygon equals 360. A triangle’s equals 180. Why?
What are good math and geometry books for woodworkers?
Could have asked that in the topic, but I’m guessing more read this with the one I chose.

Because it's not true? The sum of the interior angles of a polygon (in degrees) is equal to 180 * (# of vertices - 2):

Try, The Woodworkers Guide to Shop Math, by Tom Begnal. My son is just startng geometry and we have found several usefull web sites. Good luck.
