Description
This hinged model has two triangular pieces with a greenish plastic top.
The four triangular pieces of two models denoted by MA.304723.755 and MA.304723.760 may be arranged to form a parallelogram (in two ways) and a triangle (in two ways). They form a partially hinged dissection.
Objects MA.304723.755, MA.304723.760, and MA.304723.804 form model 6TQ (angle bisectors of a triangle). A drawing for this model, dated April 23, 1932, is in 1979.3002.55, folder 2.
This model alone also illlustrates Wheeler's model 2TT, an obtuse triangle converted into an acute triangle with the same base. A drawing for this model, dated April 26, 1932, is in 1979.3002.55, folder 2. Another related drawing in the same folder is dated April 3, 1932.
