You want to show that ∆ ART ≅ ∆ PEN,
(а) 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) ?
