three line segments have measures of 4 units, 6 units, and 8 units. Will the segments form a triangle?
Oliga [24]

Given:

Three line segments have measures of 4 units, 6 units, and 8 units.

To find:

Will the segments form a triangle?

Solution:

We know that three line segments can form a triangle if the sum of two smaller sides is greater than the largest side.

Three line segments have measures of 4 units, 6 units, and 8 units. Here, the measure of the largest sides is 8 units.

The sum of two smaller sides is

4+6=10

4+6>8

Since the sum of two smaller sides is greater than the largest side, therefore the segments will form a triangle.
