Question

look at this shape: shape on grid which image shows a rotation? images a, b, c with labels a, b, c

Explanation:

Step1: Recall rotation definition

Rotation is a transformation that turns a figure around a fixed point, changing its orientation. The original shape has a "notch" on the top - left.

Step2: Analyze each option

• Option A: The orientation of the shape (the position of the notch) is a 90 - degree rotation (or other rotation) from the original. The original shape's notch is at the top - left, in A the notch is at the bottom - right, which is consistent with a rotation.
• Option B: The orientation of the notch (top - right) does not match a rotation of the original (top - left notch). It looks more like a reflection or a different transformation.
• Option C: This looks like a translation (slide) of the original shape, as the orientation (notch position) is the same as the original.

Answer:

A. Option A
