Question

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

Explanation:

Step1: Recall Reflection Definition

A reflection (flip) of a shape creates a mirror image across a line, where corresponding points are equidistant from the line of reflection, and the shape is reversed (left-right or top-bottom flip).

Step2: Analyze Each Option

• Option A: The shape appears rotated or translated, not a mirror image. The orientation and position don’t match a reflection.
• Option B: This looks like a translation (slide) of the original shape, maintaining the same orientation, not a reflection.
• Option C: The shape is reversed (mirror image) relative to the original, with corresponding points symmetric across an implied vertical or horizontal line. This matches the reflection definition.

Answer:

C
