A Regular Polygon
Pentagon A+
It is a regular 10 sided decagon
A [regular] hexagon.
If it is a regular polygon with each interior angle of 120 degrees then it is an hexagon which will have 0.5((6^2)-3*6) equals 9 diagonals
The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees.
With any regular polygon it is 180 minus interior angle times number of sides equals 360 degrees
It will have 8 sides and it is called a regular octagon.
2700⁰/180⁰ = 15 (triangles)So the polygon has 17 sides.
