Question

Which postulate or theorem proves that △ RNM and △ QNP are congruent?

Answer 1

SAS since ∠RNM is congruent ∠PNQ by vertical angles which will give you the angle you need for SAS.

Answer 2

Answer:

B) SAS congruence postulate  

Step-by-step explanation:

We have marked that RN and NQ are congruent.  We also have marked that MN and NP are congruent.

∠MNR≅∠QNP because they are vertical angles.  Vertical angles are opposite angles that share only a vertex; these are vertical angles so they are congruent.

This gives us two sides and an included angle; this is SAS.
