WebMay 4, 2011 · Sorted by: 1. You compute the center of gravity of your polygon. You translate it to the origin so that your center of gravity has (0,0) as coordinate. Then for each vertex of coordinate (i, j) you check that there is a vertex that has coordinates (-i, -j). This will prove that your polygon is symmetric indeed. Rotational symmetry of order ... C n is the rotation group of a regular n-sided polygon in 2D and of a regular n-sided pyramid in 3D. If there is e.g. rotational symmetry with respect to an angle of 100°, then also with respect to one of 20°, the greatest common divisor of 100° and 360°. See more Rotational symmetry, also known as radial symmetry in geometry, is the property a shape has when it looks the same after some rotation by a partial turn. An object's degree of rotational symmetry is the number of distinct … See more Formally the rotational symmetry is symmetry with respect to some or all rotations in m-dimensional Euclidean space.

Each regular polygon has as many lines of symmetry as it has sides.

For regular polygons with n sides, the order of rotation is _____. o Find the degrees of rotation by dividing 360o by the number of sides. WebThe correct option is D 72∘. The angle of rotation of an n sided regular polygon is given by 360∘ n. A pentagon has 5 sides. Angle of rotation of a regular pentagon = 360∘ 5 =72∘. So, if you rotate the pentagon by an angle of 72∘, then it will look identical to the initial figure. Suggest Corrections. chelsea dfw
