What is dilation in geometry?

• A transformation that changes the size of a figure but keeps its shape the same.

• A process that rotates a figure around a point.

• A method of reflecting a figure across a line.

• A technique for translating a figure to a different location.

What is a rotation in geometry?

• A transformation that turns a figure around a fixed point at a certain angle.

• A type of reflection that flips a figure over a line.

• A dilation that enlarges or reduces a figure proportionally.

• A translation that slides a figure from one position to another.

What is a translation in geometry?

• A transformation that rotates a figure around a point.

What is the scale factor in dilation?

• The scale factor is the ratio of the size of the image to the size of the original figure.

• The scale factor is the difference in size between two figures.

• The scale factor is the sum of the dimensions of the original figure.

• The scale factor is the area of the image divided by the area of the original figure.

An image is dilated at a scale factor of 1.5. This means the dilation is an enlargement and the dilated image will be bigger. True or False?

• True

• False

• It depends on the original size

• The image will be smaller
