In ∆ABC, ∠A = 30° , ∠B = 40° and ∠C = 110°. In ∆ PQR, ∠P = 30° , ∠Q = 40° and ∠R = 110° . A student says that ∆ABC ≅ ∆PQR by AAA congruence criterion. Is he justified? Why or why not?

You want to show that ∆ART ≅ ∆PEN: (a) If you have to use SSS criterion, then you need to show: (i) AR = (ii) RT = (iii) AT = (b) If it is given that ∠ T = ∠ N and you are to use SAS criterion, you need to have:(i) RT = and (ii) PN = (c) If it is given that AT = PN and you are to use ASA criterion, you need to have: (i) ? (ii) ?

Which congruence criterion do you use in the following? (a) Given: AC = DF, AB = DE, BC = EF So If ∆ ABC ≅ ∆ DEF (b) Given: RP = ZX, RQ = ZY, ∠PRQ = ∠XZY So ∆ PQR ≅ ∆ XYZ (c) Given: ∠MLN = ∠FGH, ∠NML = ∠HFG, ML = FG So ∆LMN ≅ ∆GFH (d) Given: EB = BD, AE = CB, ∠A = ∠C = 90° So ∆ABE ≅ ∆CDB
