What is a dilation?

Back

A dilation is a transformation that changes the size of a shape but not its shape, using a scale factor.

What is a scale factor in dilation?

Back

The scale factor is a number that describes how much a figure is enlarged or reduced during a dilation.

What is a reflection?

Back

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

What is a non-rigid motion?

Back

A non-rigid motion is a transformation that changes the size of a shape, such as dilation.

What is a rigid motion?

Back

A rigid motion is a transformation that preserves the shape and size of a figure, such as translation, rotation, and reflection.

How do you determine the scale factor of a dilation?

Back

The scale factor can be determined by dividing the length of a side of the image by the length of the corresponding side of the original figure.
