Question

which figure has rotational symmetry?

Explanation:

Step1: Recall rotational symmetry definition

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

Step2: Analyze option A (heart - shaped)

A heart - shaped figure does not look the same after any rotation less than 360°.

Step3: Analyze option B (cross - like figure)

If we rotate this figure by 90°, 180°, 270° etc., it looks the same. It has rotational symmetry.

Step4: Analyze option C (arrow - shaped)

An arrow - shaped figure does not look the same after any rotation less than 360°.

Step5: Analyze option D (triangle - shaped)

This non - equilateral triangle does not look the same after any rotation less than 360°.

Step6: Analyze option E (crescent - shaped)

A crescent - shaped figure does not look the same after any rotation less than 360°.

Answer:

B. The cross - like figure
