In `triangle ABC, AC gt AB`. AB is extended to P and AC is extended to Q. Prove that, `angle PBC lt angle QCB`.

In a triangle ABC , the sides AB and AC are extended to P and Q respectively. The bisectors of angle PBC and angle QCB intersect at a point R. If angle R= 66^@ , then the measure of angle A is : त्रिभुज ABC में, AB और AC भुजाओं को क्रमशः P और Q तक बढ़ाया जाता है| angle PBC तथा angle QCB के द्विभाजक एक बिंदु R पर मिलते हैं | यदि angle R= 66^@ , है, तो कोण A का मान ज्ञात करें |
