What is the area of a regular octagon with a side length of 5 meters and a distance from the center to a vertex of 6.5 meters?
101.2 m
A general pentagon may have no symmetries at all. A regular pentagon has five symmetry axes - each one connecting a vertex with the middle of the edge opposite this vertex. A regular pentagon also has rotational symmetry - if you rotate it by any multiple of 72 degrees clockwise or anti-clockwise you get a regular pentagon as well. Please also see the related link below.
A regular pentagon has exactly five lines of symmetry. Each line of symmetry passes through one vertex and the midpoint of the opposite side. Additionally, these lines of symmetry reflect the pentagon across its center, ensuring that both halves are mirror images of each other. Thus, the regular pentagon is the simplest shape with this characteristic.
At most 5, since all symmetry lines must pass by a vertex. It has 5 if and only if the pentagon is regular.
For a regular pentagon, draw a segment from each vertex to the midpoint of the side length directly opposite, there by cutting it in half.
If the distance from the centre of the pentagon to a vertex is r cm then the length of the arc is 0.4*pi*r cm

A regular pyramid has a regular polygon base and a vertex over the center of the base. By:Cherrylvr :)
In a regular pentagon, the lines of symmetry are drawn from each vertex to the midpoint of the edge directly opposite the vertex, so there are five in all.

Assuming that radius would be the length from any vertex to the center of a figure, a regular hexagon. It can be divided into six congruent equilateral triangles.
