Symmetries in Shapes — Quiz

Question 8 • Geometry

For which shape is 45 degrees the smallest angle of rotational symmetry?

Answer

Image with description A tall parallelogram. There is a dot in the center.

Image with description A regular 14-sided figure with 7 interior reflex angles and 7 interior acute angles. There is a dot in the center.

Image with description A block figure that looks like a square with a block arrow pointing left from the middle of its left side and a block arrow pointing right from the middle of its right side. There is a dot in the center of the figure.

Image with description A block figure that looks like a sun. It is a circle wit 8 triangles surrounding it to look like sun rays. There is a dot in the center.

Explanation

A rotational symmetry angle is the smallest turn that makes a shape line up with itself. The sun has 8 evenly spaced rays, so its smallest such turn is 360° ÷ 8 = 45°. Therefore, the shape with 8 rays is the correct choice.
