A regular pentagon has Schläfli symbol {5} and interior angles of 108°. A regular pentagon has five lines of reflectional symmetry, and rotational symmetry of order 5 (through 72°, 144°, 216° and 288°). The diagonals of a convex regular pentagon are in the golden ratio to its sides.

To compute the internal angle of a pentagon: Divide 360° by the number of sides: 360°/5 = 72°. Subtract 72° from 180° to get the internal angle of a pentagon: 180° - 72° = 108°. It follows that the sum of internal angles in a pentagon equals 5 × 108° = 540°. Hanna Pamuła, PhD
