Description
This is Wheeler's model 4Q. It shows an inscribed quadrilateral in four pieces. Each piece is a section of a circle. It is divided into segments of two colors of plastic, so that there is a yellow triangle with a vertex at the center of the circle and a lune in another color. The model is shown in drawing in 1979.3002.55, folder 1, and dated April 9, 1932. The four parts can be permuted six ways to form six different inscribed quadrilaterals all inscriptible in the same circle.
