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.

Can the side lengths 3, 5, and 8 form a triangle?

Back

No, because 3 + 5 is not greater than 8.

What is the range of values for the third side of a triangle with sides 8 and 15?

Back

The third side must be between 7 and 23.

Front

Given two sides of lengths 7 ft and 13 ft, what is the range for the third side?

Back

The third side must be more than 6 but less than 20.

Front

Will the side lengths 4, 5, and 10 form a triangle?

Back

No, because 4 + 5 is not greater than 10.
