PLS HELP:(

Which statement is not used to prove that ΔABC is similar to ΔADE?

triangles ABC and ADE in which point E is between points A and C on segment AC and point D is between points A and B on segment AB, angle A is a right angle

AC is a transversal line passing ED and CB.
Angle A is congruent to itself, due to the reflexive property.
Segments ED and CB are parallel.
The sum of angles A and B are supplementary to angle C.
