Question

Two sides of an isosceles triangle have lengths of 3 and 6. What could be the length of the third side?

Answer 1

The third side could be only `6`.

Explanation:

As the two sides of an isosceles triangle have lengths `3` and `6`, the length of the third side is `6`.

Note that as the triangle is iscsceles the third side would be equal to either of them i.e, `3` or `6`.

But as sum of two sides in any triangle should be greater than the third, ypu cannot form a triangle if third side is `3`.

Hence, the third side can only be `6`.
