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 has a mirror - like appearance. The orientation of the shape changes such that left and right (or up and down depending on the axis of reflection) are reversed.

Step2: Analyze option A

Option A shows a rotation of the original triangle, not a reflection. The orientation of the triangle's vertices is not a mirror - image of the original.

Step3: Analyze option B

Option B shows a reflection. If we consider a vertical line of reflection, the left - right orientation of the triangle is reversed compared to the original, which is characteristic of a reflection.

Step4: Analyze option C

Option C shows a rotation of the original triangle, not a reflection. The overall orientation of the triangle's vertices is not a mirror - image of the original.

Answer:

B.
