Explanation:

1. First blank (transformation that flips a shape over a line)

In geometry, the transformation that flips a shape over a line to form a mirror image is known as a reflection. This is a fundamental concept in geometric transformations where the line is called the line of reflection.

A dilation is a transformation in geometry that changes the size of a figure while keeping its proportions (shape) the same. It either enlarges or reduces the figure based on a scale factor.

When a shape is dilated from the origin with a scale factor greater than 1, each coordinate of the vertices of the shape is multiplied by a number greater than 1. This results in the shape being enlarged (getting bigger) while maintaining its original shape and proportions.

Answer:

reflection
