Question

Which postulate can be used to prove triangle JLK and triangle MLK are congruent if JK and LM are congruent and parrallel. Answers:

AAS

SSS

SSA

SAS

Answer 1

SSS could work

Answer 2

This is a parallelogram

Answer 3

SAS

Answer 4

hint :- Two Sides are congruent already, one by reflexive property, and another is given.

Answer 5

I think its SSS

Answer 6

SSS is incorrect here

Answer 7

look at rajee diagram, he has it correct :)

Answer 8

I see the diagram helped explain better its SAS

Answer 9

thanks

Answer 10

why not SSS ?

Answer 11

looks right to me but can you have two answers? in a multiple choice question

Answer 12

its not SSS cuz LJ \(\cong\) MK is not either given or directly obvious here. Once a triangle is provben congruent using one theorem, all other theorems will work.

Answer 13

but they have given JK and LM are parallel and congruent . Doesn't that automatically makes JL and MK congruent
