A regular pentagon has 5 equal edges and 5 equal angles. ... 9 -ennea- Extending the system up to 999 is expressed with these prefixes. ... 70: heptaconta-700 ...
[5] The regular heptagon belongs to the D 7h point group (Schoenflies notation), order 28. The symmetry elements are: a 7-fold proper rotation axis C 7, a 7-fold improper rotation axis, S 7, 7 vertical mirror planes, σ v, 7 2-fold rotation axes, C 2, in the plane of the heptagon and a horizontal mirror plane, σ h, also in the heptagon's plane ...
The interior angle concept can be extended in a consistent way to crossed polygons such as star polygons by using the concept of directed angles.In general, the interior angle sum in degrees of any closed polygon, including crossed (self-intersecting) ones, is then given by 180(n–2k)°, where n is the number of vertices, and the strictly positive integer k is the number of total (360 ...
As n approaches infinity, the internal angle approaches 180 degrees. For a regular polygon with 10,000 sides (a myriagon) the internal angle is 179.964°. As the number of sides increases, the internal angle can come very close to 180°, and the shape of the polygon approaches that of a circle. However the polygon can never become a circle.

The 30°–60°–90° triangle is the only right triangle whose angles are in an arithmetic progression. The proof of this fact is simple and follows on from the fact that if α, α + δ, α + 2δ are the angles in the progression then the sum of the angles 3α + 3δ = 180°. After dividing by 3, the angle α + δ must be 60°. The right angle ...
