What is the Triangle Inequality Theorem?

Back

The sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Front

If the lengths of two sides of a triangle are 8 and 15, what is the range of possible lengths for the third side?

Back

The third side must be greater than 7 and less than 23.

Front

What is the minimum length of a side of a triangle if the other two sides are 10 and 14?

Back

The minimum length must be greater than 4.

Front

Can a triangle have sides of lengths 1, 2, and 3?

Back

No, because 1 + 2 is not greater than 3.
