A polygon with nine vertices also has nine sides, and is therefore a "nonagon".
They have nine sides, and nine internal angles.
A nonagon has nine sides, nine angles and nine corners (vertices).
A 9-gon is a polygon with nine sides and nine angles
A figure or polygon having nine sides and nine angles.
do you mean Nonagon. It is a nine sided polygon, edges and vertices - 9, internal angles 140o
It is: 40 degrees
A nectagon is a polygon with nine sides and nine angles. It is a type of nonagon, which is a polygon with any number of sides greater than four. The sum of the interior angles of a nectagon is 1260 degrees, calculated using the formula (n-2) x 180, where n represents the number of sides.
A shape with 9223372036854775808 sides is called a nonagon. A nonagon is a polygon with nine sides and nine angles. It is a regular nonagon if all its sides and angles are equal. The number of sides in a polygon determines its name, such as a triangle (3 sides), quadrilateral (4 sides), pentagon (5 sides), hexagon (6 sides), heptagon (7 sides), octagon (8 sides), and so on.
1,260 Complete this formula 180(n-2) n is for the number of sides in the polygon.
Such a polygon is said to be a "regular" polygon, meaning that all its sides are equal and all its angles are equal, so we have; equilateral triangle; square; pentagon; hexagon; heptagon;octagon;nonagon;decagon - to give but the first nine possibilities. The next one would have 11 equal sides and angles, and I don't know its name.
The sum of the exterior angles of any polygon - however many sides it has and whether it is convex or concave - is always 360 degrees.
