What is the order of rotational symmetry of an equilateral triangle, circle,rectangular prism , rectangular pyramid , triangular prism , triangular pyramid, square , cuboid , isoceles triangle , scalene triangle, cone , cylinder. please give the answer soon :-) :-) :-) :-)

Dear student,

Please find below the solution to the asked query:

A figure has rotational symmetry if it can be rotated around a point so that resulting figures match the original figure. The point around which you rotate is called the center of rotation, and the smallest angle you need to turn is called the angle of rotation.  The number of positions a figure can be rotated to, without bringing in any changes to the way it looks originally, is called its Order of Rotational Symmetry.The order of rational symmetry of various figures is given below:     FIGURES                                  Order of Rotational symmetry Equilateral triangle:                                        3      Circle                                                           infinite                                                             Triangular prism                      Planes of Symmetry for Triangular prism are four when it is equilateral.                                                          It is two when it is isosceles. It is one when it is scalene.                                           Square                                                            4                        Cuboid                                      The cuboid  with two rectangular faces and two square faces has                                                           a rotational symmetry of order 2 about the axis  of symmetry                                                                 Isoscles triangle                                            1      Scalene triangle                                            1      Cone                                      The order of rotational symmetry is infinite about its axis.
