Question

Which of the following could not be the side lengths of a triangle?
*
9, 5, 5
4, 9, 5
4, 3,6

Answer 1

The side lengths of a triangle must follow the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

In the case of the options provided, the side lengths that could not be the side lengths of a triangle are:

4, 3, 6

This is because the sum of the two shorter sides (4 + 3) is not greater than the longest side (6).
