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, but its orientation changes.

Step2: Analyze Option A

In Option A, the shape has been turned (rotated) around a point. The relative lengths of the sides and the angles between them are the same as in the original shape, but its orientation is different.

Step3: Analyze Option B

Option B is a translation (slide) of the original shape. The orientation and the relative position of the sides are the same as the original, just in a different location on the grid.

Step4: Analyze Option C

Option C is also a translation. The shape has been moved to a different position on the grid without any change in its orientation.

Answer:

A.
