Answer :

A. Prove that QR ≅ QR by reflexive property

Nikki is going to use SSS Property, which is Side, Side, Side. This means that, given two pairs of sides are congruent, you will have to find out the last side, which is the same side. This means that it is congruent with itself (since both triangles share the same side), and uses the reflexive property.

hope this helps
