Question

if two side of triangle are 6cm and 1.2cm the length of its third side cannot be​

Answer 1

Given, the length of two sides of a triangle are 5 cm and 1.5 cm, respectively.

Let sides AB = 5 cm and CA = 1.5 cm

We know that, a closed figure formed by three intersecting lines (or sides) is called a triangle, if difference of two sides < third side and sum of two sides > third side

∴ 5-1.5 < BC and 5+1.5 > BC

⇒ 3.5 < BC and 6.5 > BC

Here, we see that options (a), (b) and (c) satisfy the above inequality but option (d) does not satisfy the above inequality.
