Question

look at this shape: image of a blue triangle on a grid which image shows a reflection? images labeled a, b, c with blue triangles on grids buttons labeled a, b, c

Explanation:

Step1: Recall Reflection Definition

A reflection (or flip) is a transformation that creates a mirror image of a figure across a line (axis of reflection). The reflected figure should be congruent and a mirror - reverse of the original.

Step2: Analyze Each Option

• Option A: The triangle in option A does not appear to be a mirror image of the original triangle. The orientation and position do not match the expected reflection.
• Option B: The triangle in option B is a mirror image of the original triangle. If we imagine a vertical or horizontal line of reflection (depending on the grid), the triangle in B is symmetric to the original with respect to that line.
• Option C: The triangle in option C seems to be a translation (slide) or a rotation rather than a reflection, as it does not have the mirror - image property of the original triangle.

Answer:

B. Option B
