You want to show that `DeltaART cong DeltaPEN,`
(a) If you to use `SSS` criterion, then 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) ?

Explanation

Acording to SSS criterion


\Delta ART\cong\Delta PEN


i) `AR=PE`


ii) `RT=EN`
