Question

look at this shape: which image shows a reflection?

Explanation:

Step1: Recall reflection concept

A reflection flips a shape across a line. The shape's size and shape remain the same, but its orientation changes.

Step2: Analyze Option A

Option A is identical to the original shape, which means it is not a reflection but a translation or no transformation.

Step3: Analyze Option B

Option B shows the shape flipped horizontally compared to the original shape. This is a reflection.

Step4: Analyze Option C

Option C shows the shape rotated, not reflected.

Answer:

B.
