I got some pleasant feedback:

A most assuredly fine paper defining the coordinate system.

Paragraph 11 the triangle overlay may be off the center you intended.

If you moderated one or two of the personal notes, paragraph 38 "'I 
NOTICED THAT THEIR' StraightLineDistances..." it will be ready to be 
part of every trigonometric curriculum.

My reply:

Paragraph 11 is the triangle (1,2,3), not centered at the origin of the 
coordinate system. You can count the edge length equals six and the area 
equals 6^2 = 36.
