- 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.
