# Nonagon Interior Angles

### A polygon is a plane shape bounded by a finite chain of straight lines.

Nonagon interior angles. The interior angles of a triangle add up to 1800. For a nonagon n9. And there are nine angles. All sides are the same length congruent and all interior angles are the same size congruent.

But if its a regular nonagon then every interior angle is 140a0. Learn how to determine the sum of interior angles of a polygon. Nonagonstudio specializes in producing professional standard cad drawings high quality photo realistic 3d renderings 360 panorama view and 3d animation. Equal sides equal sides.

A regular polygon is a polygon whose sides are congruent. To find the measure of the interior angles we know that the sum of all the angles is 540 degrees from above and there are five angles so the measure of the interior angle of a regular pentagon is 108 degrees. The properties of regular nonagons. Its interior angles always add up to 1260a0 so it could have several right angles in it.

Interior angles of polygons an interior angle is an angle inside a shape. To find the measure of the angles we know that the sum of all the angles is 1260 degrees from above. A short line in the middle of each side of a shape means that the sides are all the same length. A regular nonagon has nine equal sides and nine equal interior angles.

So the measure of the angle of a regular nonagon is 140 degrees.
