Description:

To show relationships among planes and angles, A. H. Wheeler designed a series of what he called platform models.This colorful plastic model is one of them. It shows two angles not in the same plane that have sides that are respectively parallel and lying on the same side of the straight line joining their vertices. The angles are equal..

A paper tag on the model reads: 2A.. Another paper tag reads: A. Harry Wheeler.
