Given that StartFraction A B Over D E EndFraction = StartFraction B C Over E F EndFraction = one-half, complete the statements to show that △ABC ~ △DEF by the SAS similarity theorem.

Horizontal and vertical lines are .

So, angles are right angles by definition of perpendicular lines.

All right angles are .

Therefore, △ABC ~ △DEF by the SAS similarity theorem.
