In Δ PQR ≅ Δ EFD then ED =

In triangle ABC and PQR three equality relations between some parts are as follows:

AB = QP, ∠B = ∠P and BC = PR

State which of the congruence conditions applies:

In triangles ABC and PQR, if ∠A=∠R, ∠B=∠P and AB=RP, then which one of the following congruence conditions applies:

In Δ PQR ≅ Δ EFD then ∠E =

In a Δ ABC, if AB = AC and BC is produced to D such that ∠ACD =100°, then ∠A =
