Question

look at this shape: which image shows a reflection?

Explanation:

Step1: Recall reflection property

In a reflection, the shape flips over a line of reflection and has the same size and shape, but the orientation changes. The left - right or up - down orientation is reversed.

Step2: Analyze Option A

Option A shows a rotation of the original shape, not a reflection. The angles and orientation are changed in a rotational manner.

Step3: Analyze Option B

Option B shows a reflection. If we consider a vertical line of reflection, the original shape and this image are mirror - images of each other. The orientation is reversed in a way consistent with reflection.

Step4: Analyze Option C

Option C shows a different transformation, likely a combination of rotation and translation, not a reflection.

Answer:

B.
