What is translation in geometry?

Back

Translation is a transformation that moves every point of a shape the same distance in a specified direction.

What is rotation in geometry?

Back

Rotation is a transformation that turns a shape around a fixed point, called the center of rotation, by a certain angle.

What is reflection in geometry?

Back

Reflection is a transformation that flips a shape over a line, creating a mirror image.

What is dilation in geometry?

Back

Dilation is a transformation that enlarges or reduces a shape by a scale factor relative to a center point.

What is the scale factor in dilation?

Back

The scale factor is the ratio of the size of the image to the size of the original shape in a dilation transformation.

How do you represent a dilation algebraically?

Back

A dilation can be represented as (x, y) → (kx, ky), where k is the scale factor.
