(i) In ∆ABC and ∆PQR, we have
∠A = ∠P
∠B = ∠Q
and    ∠C = ∠R
∆ABC ~ ∆PQR
[Using AAA similar condition]
(ii) In ∆ABC and ∆QRP, we have
                            
∴                
[Using SSS similar condition]
(iii) No.
(iv) In ∆MNL and ∆QPR, we have

and    ∠NML = ∠PQR
∴   ∆MNL ~ ∆QPR
[Using SAS similar condition]
(v)    No.
(vi)    In ∆DEF and ∆PQR, we have
∠D = ∠P
∠E = ∠Q
and    ∠F = ∠R
∴ ∆DEF ~ ∆PQR
