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. The distance of each point from the line of reflection in the original shape is the same as the distance of the 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 the given shape flipped horizontally. The relative positions of the vertices and the overall shape are consistent with a horizontal reflection.

Step3: Analyze Option B

Option B is a rotation of the original shape, not a reflection. The orientation and position of the shape are different from what would be expected in a reflection.

Step4: Analyze Option C

Option C is the same as the original shape, just in a different position. It is not a reflection as there is no flipping over a line.

Answer:

A. Option A
