Question

You want to show that ΔART≅ΔPEN,If it is given that ∠T=∠N and you are to use SAS criterion, you need to have
(a) RT =
(b) PN =

Answer 1

Hey mate.
Here is your answer-

【Ans.(a)】- RT = EN

【Ans.(b)】- PN = AT

Hope it helps!!!!!

Answer 2

Using SSS criterion,

ΔART≅ΔPEN

here

both are congruent

so

A corresponds to P

R corresponds to E

T corresponds to N

therefore,

RT=EN

PN=AT
