16+ Regular Nonagon Sides Background. Sum of interior angles = (n−2) × 180°. Along with nine sides, a nonagon has nine vertices.
Polygons from image.slidesharecdn.com Try this adjust the nonagon to find the exterior angle of a regular decagon, we use the fact that the exterior angle forms a linear. A regular nonagon has an internal angle of 140 degrees each. A regular nonagon is a shape where all nine sides are the same length, which consequently means that all internal angles are equal at 140 degrees.
Each interior angle of a regular nonagon is 140 degrees.
