Category:Symmetry Group of Regular Pentagon

This category contains examples of Symmetry Group of Regular Pentagon.

Let $\PP = ABCDE$ be a regular pentagon.

The various symmetry mappings of $\PP$ are:

the identity mapping $e$

the rotations $r, r^2, r^3, r^4$ of $72^\circ, 144^\circ, 216^\circ, 288^\circ$ around the center of $\PP$ anticlockwise respectively

the reflections $t_A, t_B, t_C, t_D, t_E$ in the lines through the center of $\PP$ and the vertices $A$ to $E$ respectively.

This group is known as the symmetry group of the regular pentagon.
