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 such that left - right or up - down positions are reversed with respect to the line of reflection.

Step2: Analyze Option A

Option A shows a rotation of the original triangle, not a reflection. The orientation of the triangle in Option A is different from what would be obtained by reflecting it over a vertical or horizontal line.

Step3: Analyze Option B

Option B shows a reflection of the original triangle. If we consider a vertical line of reflection, the left - right orientation of the triangle is reversed as expected in a reflection.

Step4: Analyze Option C

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

Answer:

B.
