Which congruence criterion do you use in...

Which congruence criterion do you use in the following? (a) Given: `AC = DF AB = DE BC = EF So, Delta ABC \congDelta DFE` (b) Given `ZX = RP RQ = ZY ? < PQR = < XYZ So, Delta PRQ \_cong?] Delta XYZ` (c) Given: ? ? `< MLN = < FGH ML = FG` So, (d) GIven: `EB = DB AE = BC ? < A = < C 90^@ So, Delta ABE [\_cong?] Delta CDB`
