Question

1. a translation is a

flip
change in shape
change in size
slide

Explanation:

A translation in geometry is a type of transformation where every point of a figure or space is moved in a given direction by the same distance. It is essentially a "slide" of the figure without rotation, reflection, or resizing. A "flip" refers to a reflection, a "change in shape" would involve a non - rigid transformation (not translation), and a "change in size" is a dilation.

Answer:

slide
