Question

The lengths of two sides of a triangle are 5 and

7. Which measurement cannot be the length of
the third side?
A) 5 B) 6
C) 4 D) 2

Answer 1

D) 2

Explanation:

A Triangle two sides added together must always be greater than the other side.

It can not be 2 because the two sides of a triangle added are not greater than the other side.

Here 5 + 2 = 7 which is not greater than 7 on the other side, so 2 fails.
