What is the result of a reflection in geometric transformations?

A reflection in geometric transformations produces a mirrored image of the original figure. This transformation flips the figure over a line, known as the line of reflection, creating a symmetrical counterpart on the opposite side of the line. Each point of the original figure moves to a corresponding point on the opposite side of the line, maintaining the same distance from the line. This results in a figure that is identical in shape and size to the original but oriented in the opposite direction.

In contrast, the other options describe different kinds of transformations or outcomes that do not apply specifically to reflection. For example, scaling refers to enlarging or reducing the size of a figure (as in the first choice), while a shift in position with no change in shape describes translation. A combination of multiple transformations usually refers to sequences of transformations such as rotation and reflection, but this is not what is characterized purely by reflection alone.
