Triangle ABC can be taken to a triangle A'B'C' using rigid motions and a dilation. Select ALL the equations that are true.

Is line BC parallel to line DE? Choose the best justification.

• Line BC is parallel to line DE because triangle ABC is a dilation of triangle ADE by a scale factor of 3 from point A.

• Line BC is parallel to line DE because triangle ABC is a dilation of triangle ADE by a scale factor of 2 from point A.

• Line BC is not parallel to line DE because there is no dilation that sends triangle ADE to triangle ABC.

Triangle ABC is similar to triangle EFD. What scale factor is required to dilate triangle ABC so that its image , A'B'C' is congruent to triangle EFD?
