10. In APQR, PQ = 3 cm, QR = 4 cm and PR = 5 cm. Name the smallest
and largest angles of the triangle.f
​

Answer 1

We know the fact,
the angle opposite to smallest side is always smaller.
So, in given triangle PQR, PQ = 3 cm, which is the smallest side. So /_PRQ is smallest.

Also, the We know the fact,
the angle opposite to largest side is always greater.
So, in given triangle PQR, PR = 5 cm, which is the longest side. So /_PQR is greatest.
