Question

look at this shape: which image shows a reflection? a b c a b c

Explanation:

Step1: Recall reflection concept

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 a rotation of the original triangle, not a reflection. The orientation of the triangle's vertices has changed in a rotational manner.

Step3: Analyze Option B

Option B shows a reflection. If we consider a vertical line of reflection, the original triangle is flipped over this line to get the triangle in Option B. The vertices are in the mirror - image positions.

Step4: Analyze Option C

Option C shows the same triangle as the original one, just in a different position. It is not a reflection.

Answer:

B.
