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) ?
