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) ?

(a) Using SSS criterion, ∆ART ≅ ∆PEN
(i) AR = PE (ii) RT = EN (iii) AT = PN
(b) Given: ∠T = ∠N
Using SAS criterion, ∆ART ≅ ∆PEN
(i) RT = EN (ii) PN = AT
(c) Given: AT = PN
Using ASA criterion, ∆ART ≅ ∆PEN
(i) ∠RAT = ∠EPN (ii) ∠RTA = ∠ENP
