Exploring Dilations in the Coordinate Plane

Explore dilations on the following graph by sliding the scale factor button. Then answer the questions below.

Dilations

Triangle ABC is the preimage, and triangle A'B'C' is the image after dilation.

When the scale factor is a decimal less than one, how does triangle A'B'C' compare to triangle ABC?

A'B'C' is smaller and located below ABC. The two triangles are congruent. A'B'C' is larger and located above ABC.

Triangle ABC is the preimage, and triangle A'B'C' is the image after dilation.

When the scale factor is 2, how does triangle A'B'C' compare to triangle ABC?

A'B'C' has side lengths 2 times larger than ABC and is above ABC. The two triangles are congruent. A'B'C' is smaller and located below ABC. A'B'C' has side lengths 1/2 times smaller than ABC and is above ABC.
