PQR is a right angle triangle at Q and PQ : QR = 3 : 2. Which is the least angle? Triangles, ML Aggarwal Understanding Mathematics Solutions ICSE Class 9.

Given,

PQR is a right angle triangle at Q and PQ : QR = 3 : 2.

PQ = 3x and QR = 2x.

Thus, QR is the smallest side and the angle opposite to the smallest side is smallest angle.

∴ ∠P is the least angle.

Hence, ∠P is the least angle.
