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.

What is the range of possible measures for the third side of a triangle with sides measuring 7 and 11?

Back

The range is given by the inequality: 4 < x < 18.

Front

How do you determine the shortest side of a triangle?

Back

To find the shortest side, compare the lengths of all sides and identify the smallest value.

What does it mean to order sides from least to greatest?

Back

It means to arrange the side lengths in ascending order, starting with the smallest.
