Which answer is right??
Answers
Answer:
correct answer will be A.
Answer: Option A is correct.
Because Nikki is going to use SSS (Side-Side-Side) convergence criteria, she cannot take the help of ANGLES.
She can use only sides to prove the congruency by SSS. Therefore, options C and D are eliminated because they contain relationship between angles.
After proving two triangles congruent, we use C.P.C.T Criteria.
But in option B, they are using this criteria for proving the two triangles congruent. WHICH IS IMPOSSIBLE!!!
Because C.P.C.T is always used AFTER proving congruent and not FOR proving congruent. So, option B is also incorrect.
Remaining option A is correct because it states that the side QR is common(reflexive) to both the triangles and this property can be used to show the two triangles congruent.
