Question

The sides of APQR are such that PQ > QR > PR. Name the smallest and the greatest angle of triangle PQR (With reasons.)​

Answer 1

Step-by-step explanation:

In ∆PQR,  PQ = 10 cm, QR = 12 cm, PR = 8 cm [Given]  Since, 12 > 10 > 8  ∴ QR > PQ > PR ∴ ∠QPR > ∠PRQ > PQR [Angle opposite to greater side is greater]  ∴ In ∆PQR, ∠QPR is the greatest angle and ∠PQR is the smallest angle
