Nessa proved that these triangles are congruent using ASA. Roberto proved that they are congruent using AAS. Which statement and reason would be included in Roberto’s proof that was not included in Nessa’s proof? Given: B ≅ N; BC ≅ NM; C is right; M is right Prove: ABC ≅ QNM A ≅ Q because of the third angle theorem. AB ≅ QN because they are both opposite a right angle.  BC ≅ NM because it is given. C ≅ M because right angles are congruent.
