Question Video: Determining Whether a given Shape Has Rotational Symmetry or Not Mathematics

Video Transcript

Does this shape have rotational symmetry?

A shape has rotational symmetry when it still looks the same after a rotation. There’s the shape rotated 90 degrees counterclockwise. Here we’ve rotated the shape 180 degrees.

No matter how we turn this shape, it won’t look the same as our original. This means the answer to the question does this shape have rotational symmetry is no. It will not look the same after any rotation. This shape, this heart, does not have rotational symmetry.
