Object Details
- Wood, R. H.
- Description
- One of these two hinged dissection consists of five wooden pieces painted green and a sixth wooden piece, also painted green, that is a right triangle attached to the rest of the pieces so that its edges can line up with the other dissection in three ways (eg according to the length of the side of the right triangle of interest). The five pieces form Wheeler's model 5SA. The model is marked on one edge: 1928. It is marked on another edge: R.H. WOOD. The model illustrates the Pythagorean theorem.
- A second hinged dissection consists of four plain wooden pieces which can be arranged as a triangle or a trapezoid. This is model 4X in Wheeler's list of decompositions of polygons (under quadrilaterals). Compare MA.304723.762.
