A triangle can be constructed by taking its sides as:
(a) 1.8 cm, 2.6 cm, 4.4 cm
(b) 2 cm, 3 cm, 4 cm
(c) 2.4 cm, 2.4 cm, 6.4 cm
(d) 3.2 cm, 2.3 cm, 5.5 cm

Solution:

We know that

A triangle can be constructed if it satisfies the condition.

The sum of two sides is greater than the third side.

(a) 1.8 + 2.6 = 4.4

Here 4.4 is not greater than 4.4

(b) 2 + 3 = 5

5 > 4

Here 5 is greater than 4

(c) 2.4 + 2.4 = 4.4

Here 4.4 is less than 6.4

(d) 3.2 + 2.3 = 5.5

Here 5.5 is equal to 5.5

Therefore, a triangle can be constructed by taking its sides as  2 cm, 3 cm, 4 cm.
