Question

look at this shape: which image shows a rotation? a b c

Explanation:

Step1: Recall rotation concept

Rotation is turning a shape around a fixed - point. The shape's size and shape remain the same, only its orientation changes.

Step2: Analyze Option A

Option A shows the shape in a different position but with the same orientation as the original. It looks like a translation (slide) rather than a rotation.

Step3: Analyze Option B

Option B shows the shape turned around a point. The angles and side - lengths are the same as the original shape, but its orientation has changed, which is characteristic of a rotation.

Step4: Analyze Option C

Option C also looks like a translation (slide) of the original shape rather than a rotation as the orientation has not changed in a rotational way.

Answer:

B.
