Question

the length of two sides of a triangle are 6 cm and 9cm
write all the possible length of third side

Answer 1

The third side should be more than the difference between the other two sides and less than the sum of the other two sides.

6–4 = 2 cm and 4+6 = 10 cm.

So the third side should be between 2.1 cm and 9.9 cm, and if only integers are considered then the third side should be anywhere between 3 cm and 9 cm.
