Question

Is it possible to construct a triangle with lengths of its sides as given below? Give reason for your answer. 2.5 cm, 5 cm, 7 cm.

Answer 1

Answer:

If sum of two side is greater then Third side

2.5+5 > 7

5+7 > 2.5

7+2.5 > 5

Answer 2

Answer:

Yes, it's possible

Step-by-step explanation:

The property for possibility of a triangle formation states that 2 sides of a triangle should be greater than the third side

2.5cm + 5cm = 7.5cm > 7cm

2.5cm + 7cm = 9.5cm > 5cm

7cm + 5cm = 12cm > 2.5cm

In all these cases the third angle is smaller than the sum of other two angles.

Hence the triangle is possible
