Question

The angle of rotation of a figure is 36 degree. What is its order of symmetry?

Answer 1

Answer:

For the regular polygons, the Order of rotational symmetry is equal to the number of sides of the polygons. Without drawing it, can you say what the Order of rotational symmetry is for a regular decagon, a 10-sided polygon? It is Order 10, meaning you can rotate the figure 36° and match it to the original.
