**Q.5. If Î”PQR and Î”LMN are congruent under the correspondence then fill up the blanks : (i) âˆ R = .......................... (iv) âˆ QR = .......................... (ii) âˆ P = .......................... (v) âˆ QP = .......................... (iii) âˆ Q = .......................... (vi) âˆ RP = ..........................**

**Ans. **(i) âˆ R = âˆ N (iv) QR = LN
