In ∆PQR, PQ = 10 cm, QR = 12 cm, PR triangle. 8 cm. Find out the greatest and the smallest angle of the triangle.

Answer»

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.
