Transformations and Congruency

Match the following words with their description.

• A transformation that causes a figure to change in size.

• Congruent

• An image that has the same shape, but a different size after a transformation.

• Similar

• An image that has changed in shape or size after a transformation.

• Dilation

• An image that has the same shape and size after a transformation.

• Not Congruent

Determine if the two figures are similar by using transformations.

• similar; a reflection and a dilation map one figure onto the other.

• similar; a rotation and a dilation map one figure onto the other.

• similar; a translation and a dilation map one figure onto the other.
