Determine which postulate or theorem can be used to prove the pair of triangle congruent. If it is not possible to prove them congruent, select not possible. a. SAS b. SSS c. AAS d. not possible
answer is A: SAS
how many sides are equal and how many angles are equal ?
i think the two long sides are equal and the two short sides?
2 short sides equal<---correct 2 long sides , which ? central or the pair at the ends ?
pair at the ends
actually they are NOT given to be congruent. but central side is common to both triangles, hence equal for both triangles.... make sense ?
yes
now 2 pairs of sides equal -----> SS you need one more information, can u find any given information useful ....? either for sides or angles ?
ummmm
see the diagram, the angles are also given congruent, right ?
yes
so that would be A u already had SS that becomes SAS makes sense ?
yes
that is why it is SAS postulate. option a.
ok :)
