Learn what rotational symmetry is and how to find its order and angle of rotation for different geometrical shapes. See examples, worksheets, and FAQs on rotational symmetry.
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 orientations in which it looks exactly the same for each rotation.
Aug 3, 2023 · A shape is said to have a rotational symmetry if after its rotation of anything less than 360°, looks the same. This rotation can be clockwise or anticlockwise. Geometric shapes like equilateral triangles, squares, pentagons, hexagons, or any other regular polygon posses rotational symmetry.
