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. 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 is not a reflection. It looks like a translation or a non - reflective transformation as the orientation of the shape is the same as the original.

Step3: Analyze Option B

Option B is a reflection. The shape has flipped over a horizontal line (it could be a horizontal line of reflection). The relative positions of the parts of the shape with respect to the grid have changed in a way that is consistent with a reflection.

Step4: Analyze Option C

Option C is not a reflection. It is more like a rotation or a non - reflective transformation as the orientation of the shape is not consistent with a reflection of the original shape.

Answer:

B.
