• 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 parallel to line DE because triangle ABC is a dilation of triangle ADE by a scale factor of 4/3 from point A.

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

Which step is incorrect? Hint: Draw it out

• Step 3 because it is only true for triangles that if all the side lengths are proportional.

• Step 6 because the angles of a rhombuses are not always congruent.

• Step 2 because the scale factor should be AB/WX.

• Step 7 because the vertices does not line up on both vertices.
