State whether the triangle is possible to construct if
`(a) In ΔABC, m∠A = 80°, m∠B = 60°, AB = 5.5 cm`
`(b) In ΔPQR, PQ = 5 cm, QR = 3 cm, PR = 8.8 cm`

Explanation

Solution:

`(a) m∠A = 80°, m∠B = 60°
m∠A + m∠B = 80° + 60° = 140° < 180°`

So, `Δ ABC` can be possible to construct.

`(b) PQ = 5 cm, QR = 3 cm, PR = 8.8 cm`

`PQ + QR = 5 cm + 3 cm = 8 cm < 8.8 cm
or PQ + QR < PR`

So, the `Δ PQR` can not be constructed.
