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 a dilation (enlargement) of the original triangle, not a rotation as the size has changed.

Step3: Analyze Option B

Option B shows a rotation of the original triangle. The shape's size and shape are the same, and it has been turned around a point.

Step4: Analyze Option C

Option C shows a translation (slide) of the original triangle. The orientation has not changed, just its position.

Answer:

B.
