In the given figure, a circle inscribed in triangle PQR , touches its sides PQ, QR and RP at points S, T and U, respectively. If PQ = 15 cm, QR = 10 cm and PR = 12 cm, then find the length of PS, QT and RU? दी गयी आकृति में, त्रिभुज PQR के भीतर एक वृत्त स्थित है जो भुजाओं PQ, QR तथा RP को क्रमशः S, T और U बिंदुओं पर स्पर्श करता है | यदि PQ= 15 सेमी, QR =10 सेमी तथा PR = 12 सेमी है, तो PS, QT तथा RU की लंबाई कितनी होगी ?

A circle is inscribed in a triangle ABC. It touches sides AB, BC and AC at the points P,Q and R respectively. If BP = 6.5 cm, CQ = 4.5 cm and AR = 5.5 cm, then the perimeter (in cm) of the triangle ABC is : एक वृत्त किसी त्रिभुज ABC के भीतर स्थित है | यह भुजाओं AB, BC तथा AC को क्रमशः बिंदु P, Q और R पर स्पर्श करता है | यदि BP = 6.5 सेमी, CQ = 4.5 सेमी और AR = 5.5 सेमी है, तो त्रिभुज ABC का परिमाप ( सेमी में ) क्या होगा ?

A circle is inscribed in a triangle ABC. It touches sides AB, BC and AC at points P, Q and R respectively.
