Question

look at this shape: image of a triangle which image shows a reflection? images of three triangles labeled a, b, c a b c

Explanation:

Step1: Recall reflection definition

A reflection (mirror image) flips a shape over a line, creating a mirror - like copy. The original triangle has a certain orientation. Let's analyze each option:

• Option C: The triangle in option C seems to be a translation (slide) of the original triangle, as it has the same orientation and position relative to the grid (just moved), not a reflection.
• Option A: The triangle in option A has a different orientation compared to the original, but when we check the mirror - like flip, it doesn't match the reflection of the original triangle.
• 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, the triangle in B is flipped correctly compared to the original.

Answer:

B. The triangle in option B shows a reflection of the original triangle.
