Answer:
A triangle is a geometrical figure made of three sides, but the sides cannot take on any length. If the lengths of the line segments are a, b and c it is possible to create a triangle only if all three of the following conditions are satisfied. a + b > c, a + c > b and b + c > a. If the length of any one side is greater than the sum of the length of the other two, the line segments cannot be used to create a triangle.
It is possible to create a triangle using 3 line segments if the sum of the lengths of any two line segments is greater than the length of the third
