A heptadecagon is a polygon with 17 sides and 17 vertices.

Regular Heptadecagon

A regular heptadecagon is a polygon with 17 equal sides and angles.

Heptadecagon

Angles of the Heptadecagon

The sum of interior angles of a heptadecagon = (17 − 2) · 180° = 2,700°

The value of an interior angle of a regular heptadecagon is: 2,700º : 17 = 158.82º

The central angle of a regular heptadecagon measures: 360º : 17 = 21.18º

Diagonals of the Heptadecagon

The number of diagonals in a regular heptadecagon = 17 · (17 − 3) : 2 = 119

Perimeter of a Regular Heptadecagon

Perimeter = 17 · l
