Answer 1

What Theorem or postulate would you think would work here ... if any?

Answer 2

Well what are your possibilities?

Answer 3

That is one possibility ... do you know the value of two different angles in each of the triangles?

Answer 4

I will help but I won't answer it...That is not the point of this website. So let's go on. You only know one angle in each triangle so AA won't work...But what do you know one angle in each triangle are those two angles congruent?

Answer 5

Ok AA does not work because you would need two angles in MPR to be congruent to two angles in NAD. You dont have that. You do have one angle in MPR that is congruent ot one angle in NAD. Which angles do you know are congruent from the marking in the picture.
