Front

What is the triangle inequality theorem?

Back

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

Given two sides of a triangle, how can you determine the range of possible lengths for the third side?

Back

The length of the third side must be greater than the difference of the two sides and less than the sum of the two sides.
