Question

Is it possible to construct a triangle with lengths of its sides as 8 cm, 7 cm and 4 cm? Give reason for your answer.

Solution

Yes, because in each case the sum of two sides is greater than the third side.

i.e., 7 + 4 > 8, 8 + 4 > 7, 7 + 8 > 4

Hence, it is possible to construct a triangle with given sides.
