Question

look at this shape: which image shows a reflection? a b c a b c

Explanation:

Step1: Recall reflection property

In a reflection, the shape flips over a line of reflection, and the distance of each point from the line of reflection in the original shape is the same as the distance of its corresponding point in the reflected - shape from the line of reflection. Also, the orientation of the shape changes (left - right or up - down).

Step2: Analyze Option A

Option A shows a rotation of the original shape, not a reflection. The orientation of the shape has changed in a rotational manner, not a flipped - over manner.

Step3: Analyze Option B

Option B shows a reflection of the original shape. If we consider a vertical line of reflection, each point on the original shape has a corresponding point on the reflected shape at the same distance from the line of reflection, and the shape is flipped over.

Step4: Analyze Option C

Option C shows a translation of the original shape. The shape has just moved to a different position without any flipping or rotation.

Answer:

B.
