Question

Why we can not construct a triangle of given sides as 4cm ;3cm and 7 cm? Give reason:

Answer 1

Answer:

Step-by-step explanation:

In a triangle sum of two sides will always be more than the third side

If two sides are 3 and 4, then the third side should be less than 7. Here third side given is 7 which is not possible

Answer 2

Step-by-step explanation:

The sum of any 2 sides should always be greater than third side

4 cm , 3 cm === 4+3 = 7 cm which is equal to given third side.

Hence construction is not possible

[Additional info: the difference between 2 sides should be less than third side. 7 - 4 = 3 cm which is same as third side. so not possible]
