Question

look at this shape: image of a purple trapezoid on a grid which image shows a reflection? images labeled a, b, c of different trapezoid orientations

Explanation:

Step1: Recall Reflection Definition

A reflection (mirror image) flips a shape over a line, creating a mirror - like copy. The key is that corresponding points are equidistant from the line of reflection, and the shape is reversed.

Step2: Analyze Option A

Option A looks like a translation (sliding) of the original shape, not a reflection. The orientation and position change in a way consistent with moving the shape without flipping.

Step3: Analyze Option B

Option B shows a shape that is a mirror image of the original. If we imagine a vertical or horizontal line of reflection, the shape is flipped, and the corresponding sides and angles are in the correct mirror - image position.

Step4: Analyze Option C

Option C appears to be a rotation or a different transformation, not a reflection. The shape's orientation is changed in a way that is not consistent with a flip over a line.

Answer:

B
