How does the size of triangle A'B'C' compare to the size of triangle ABC?

• Triangle A’B’C’ will be smaller than triangle ABC since triangle ABC is being dilated

  by a scale factor greater than 1.

• Triangle A’B’C’ will be smaller than triangle ABC since triangle ABC is being dilated

  by a scale factor smaller than 1.

• Triangle A’B’C’ will be larger than triangle ABC since triangle ABC is being dilated

  by a scale factor smaller than 1.

• Triangle A’B’C’ will be larger than triangle ABC since triangle ABC is being dilated

  by a scale factor greater than 1.
