Question

look at this shape: which image shows a reflection? 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 is an exact copy (translation) of the original shape, not a reflection. There is no flipping over a line.

Step3: Analyze Option B

Option B shows the shape flipped over a vertical line. The left - most point of the original shape is now the right - most point in Option B, and vice - versa. This is a reflection.

Step4: Analyze Option C

Option C is a rotation of the original shape, not a reflection. The orientation change is due to turning the shape around a point, not flipping over a line.

Answer:

B. Option B shows a reflection.
