Question

Triangle ABC is shown below with line DE passing through points D and E.

Triangle ABC is shown with point D lying on side BC and point E lying on side AC. Line DE is perpendicular to side AC.

If triangle ABC is dilated by a scale factor of five about the center of the triangle to create triangle A'B'C', dilated line D'E' will

be parallel to DE

be perpendicular to DE
