Question

1. a reflection in geometry is a change in size change in shape a mirror image the moon on a body of water

Explanation:

In geometry, a reflection is a transformation that creates a mirror - image of a figure over a line (the line of reflection). It does not change the size or shape of the figure. The option "change in size" refers to dilation, "change in shape" is not a valid geometric transformation in the context of basic rigid transformations (reflection is a rigid transformation), and "the moon on a body of water" is a real - world example but not the geometric definition.

Answer:

C. a mirror image
