Question 2 (b)
You want to show that $\Delta ART\cong \Delta PEN$
If it is given that $\angle T=\angle N$ and you are to use SAS criterion, you need to have:
i) RT = and ii) PN =

Answer 1

Given: $\angle T=\angle N$
Using SAS criterion, if $\Delta ART\cong \Delta PEN$, then the corresponding sides of both the triangles must be of same length.

Hence,
i) RT = EN ii) PN = AT
