Question

In ∆PQR, PQ = 10 cm, QR = 12cm, PR = 8 cm, find the biggest and the smallest angle of the triangle.

Answer 1

in ∆PQR

since, QR is the biggest side so
angle QPR would be greatest as
(angle opposite to greatest side is greatest)

since, PR is the smallest side so
angle PQR would be smallest as
(angle opposite to smallest side is smallest)
