This video teaches the viewers how to determine whether 3 given side lengths will form a triangle using the Triangle Inequality Theorem. The first step is to add the two shortest sides. The second step is to compare the sum of the two shortest sides to the third side. If the sum is greater than the third side length, then the side lengths will form a triangle. If the sum is not greater than the third side length, then the side lengths will not form a triangle. The video has 3 practice problems at the conclusion of the video so the viewer can practice the skill of determine whether 3 given side lengths will form a triangle using the Triangle Inequality Theorem.
