Choose all statements that are true about dilations.

• Dilations cause angle measures to change.

• Dilations change the size of a shape by making it bigger or smaller.

• When you dilate by a scale factor bigger than 1, the shape increases in size.

• When you dilate by a scale factor less than 1, the shape increases in size.

• Dilations only increase the size of a shape.
