Question

look at this shape: blue l - shaped figure on grid which image shows a reflection? three grid - based blue shapes labeled a, b, c a b c

Explanation:

Step1: Recall reflection definition

A reflection (mirror image) of a shape should be a flip over a line, so the shape and its reflection are symmetric with respect to that line (like a mirror). The original shape has a "notch" on the top - right part (when looking at the original L - like shape).

Step2: Analyze each option

• Option A: The shape in A does not seem to be a reflection. The orientation and the position of the "notch" are not symmetric to the original.
• Option B: The shape in B is a mirror - image (reflection) of the original shape. If we imagine a vertical or horizontal line of reflection, the shape in B is flipped correctly compared to the original.
• Option C: The shape in C is the same as the original, not a reflection (it's a translation or just the same shape, no flip).

Answer:

B
