Question

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
(a) RT =______

(b) PN =______

Answer 1

Given that $\Delta ART\cong \Delta PEN$ and $\angle T=\angle N$

If the SAS (side angle side) criterion is used, then corresponding sides which are adjacent the equivalent angle of the triangle are equivalent.

Therefore, $RT=EN$ and

$PN=AT$
