Question

look at this shape: which image shows a reflection? a b c a b c

Explanation:

Step1: Recall reflection property

In a reflection, the shape flips over a line of reflection. The distance of each point from the line of reflection in the original shape is the same as the distance of the corresponding point in the reflected - shape from the line of reflection. Also, the orientation of the shape changes (left - right or up - down).

Step2: Analyze option A

Option A shows a rotation of the original shape, not a reflection. The orientation of the non - parallel sides is different from what would be expected in a reflection.

Step3: Analyze option B

Option B shows a reflection. If we consider a vertical line of reflection, the left and right parts of the original shape are swapped in a mirror - like fashion.

Step4: Analyze option C

Option C shows a translation (a slide) of the original shape. The orientation and relative position of the sides are the same as in the original shape, just in a different location on the grid.

Answer:

B.
