Question

sometimes, a motion appears to be a reflection when it really isnt. consider each pair of objects below. which diagram looks like a reflection across the given line of reflection but is actually done by a rotation and a translation? a original image b original image c original image

Explanation:

Step1: Analyze option a

The image in option a is just a translation of the original object. There is no rotation involved and it doesn't look like a reflection - it's just moved downwards.

Step2: Analyze option b

The leaves in option b seem to be reflected across the vertical line. But upon closer inspection, the orientation of the leaves (the order of the colors of the leaves) indicates that it is achieved by a rotation around a point near the center - vertical line and then a possible small translation. It gives the illusion of a reflection.

Step3: Analyze option c

The heart - shaped object in option c is clearly rotated around a point and then translated. But it doesn't look like a reflection as the orientation change is more obvious and the line doesn't act as a proper line of reflection.

Answer:

b
