(i) ∆ ___ADC___ ≅ ∆ABC.

(ii) BC = ___CD___.

(iii) ∠BCA = ___∠DCA___.

(iv) Line segment AC bisects ___∠A____and ____∠C___.

Fill in the blanks to make the statements true.

In Fig. 6.27,

(i) ∠TPQ = ∠____PQR____ + ∠____PRQ____

(ii) ∠UQR = ∠____QPR____ + ∠____PRQ____

(iii) ∠PRS = ∠____RPQ____ + ∠____PQR____
