Question

The lengths of two sides of a triangle are 3 cm and 6 cm. Between what two

measures should the length of the third side fall?​

Answer 1

The limits of the measure of the length of the third side of the triangle should be within $0cm < 3RD side < 9cm$.

Given

The length of one side of a triangle $=3cm$

The length of the other side of the triangle $=6cm$

Note that the sum of the lengths of any two sides of any triangle is always greater than its third side.

Also, the third side should possess a minimum length greater than zero.

Therefore, the required limits of the measure of the length of the third side of the triangle should be within the following limits.

$0cm < 3RDside < (3+6)cm\\0cm < 3RD side < 9cm$
