Question

the image is an example of which type(s) of symmetry?
a. reflectional
b. both rotational and reflectional
c. rotational
d. neither rotational nor reflectional

Explanation:

A regular pentagon (the shape in the image) has reflectional symmetry (it can be divided into two congruent halves by a line of symmetry). It also has rotational symmetry (it looks the same after a rotation of \(72^{\circ}\), \(144^{\circ}\), \(216^{\circ}\), \(288^{\circ}\) around its center). So it has both types of symmetry.

Answer:

B. Both rotational and reflectional
