Which of these figures has rotational symmetry?

Rotational symmetry means it looks the same when it is turned.

So looking at those figures, B may look like a good option but notice that the edges are not the same length - if you rotate it, the shape would not EXACTLY match on top of it's original.

Option C and D are out since they don't have any symmetrical properties. Any way you turn them would give you a different shape.

That leaves you with A: try and rotate this image 180 degrees, it should look the same.

Therefore, the figure with rotational symmetry is A

the correct answer is a
