An isonona triangle is one of four isosceles triangles with two angles , , or . Each kind can be dissected into isonona triangles, all with equal legs. The term isonona is introduced in analogy with the term isohepta [1, p. 218].


This Demonstration shows isonona triangle templates for 3D printing.
