Symmetries of a Square and an Equilateral Triangle
Symmetries of a Square and an Equilateral Triangle
In "single symmetry" mode, the Demonstration shows the action of a selected symmetry of a square or an equilateral triangle. In "composition" mode, the effect of two symmetries applied successively is shown. The set of symmetries of each figure forms a group under composition and the group multiplication table is shown in "Cayley table" mode.
