Step 1
To determine if a shape has rotational symmetry, we need to check if it looks the same after rotating it by a certain angle. In the case of a regular octagon, it does have rotational symmetry. The angle of rotation for a regular octagon is 45 degrees. This Show more…

A regular octagon is rotated about a centrally located point (as shown). How many rotations are needed to repeat the given octagon vertex for vertex, if the angle of rotation is $\begin{array}{lllll}\text { a) } & 10^{\circ} ? & \text { b) } 45^{\circ} ? & \text { c) } 90^{\circ} ? & \text { d) } 120^{\circ} ?\end{array}$ (figure not copy)
