A Polygon With 9 Sides

What is Nonagon?

A nonagon is a polygon fabricated upwards of nine sides and ix angles.

Nonagon = Nona + gon where Nona means ix and gon means sides.

The given nonagon ABCDEFGHI has sides AB, BC, CD, DE, EF, FG, GH, How-do-you-do, and IA and angles ∠A, ∠B, ∠C, ∠D, ∠East, ∠F, ∠G, ∠H, and ∠I.

The blueish line segments AC and BD are its diagonals.

In that location are total of 27 diagonals in a nonagon as shown below:

Not-examples

The following shapes are not nonagons. Let united states of america run across why?

Regular nonagon

A nonagon in which all sides are equal and all angles are equal is a regular nonagon.

Each bending of a regular nonagon is of 140°.

Irregular nonagon

A nonagon in which all sides are not equal and all angles are not equal. The measure of its angles are different but full sum of all its interior angles is always 1260°.

Fun facts about nonagons
