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 orientation of the shape changes (left - right or up - down).

Step2: Analyze Option A

Option A shows the triangle flipped horizontally compared to the original triangle. The relative positions of the vertices change in a way consistent with a horizontal reflection.

Step3: Analyze Option B

Option B is a translation (slide) of the original triangle, not a reflection. The orientation is the same.

Step4: Analyze Option C

Option C is a rotation of the original triangle, not a reflection. The orientation and position are different in a rotational way, not a reflective way.

Answer:

A. Option A
