Question

which graphs have rotational symmetry? check all of the boxes that apply.

Explanation:

Step1: Define rotational symmetry

A graph has rotational symmetry if it looks the same after a rotation of less than 360° about a point.

Step2: Analyze first graph

The first graph (a non - symmetric curve) does not look the same after rotation of less than 360° about any point.

Step3: Analyze second graph

The second graph (a V - shaped graph) does not look the same after rotation of less than 360° about any point.

Step4: Analyze third graph

The third graph (an ellipse) looks the same after a 180° rotation about its center. So it has rotational symmetry.

Answer:

The third graph has rotational symmetry.
