Watch the video for examples of the Triangle Inequality Theorem.
Triangle Inequality Theorem –– Example
Next, check to see if the following measurements would form a triangle using what you learned from the video.
1) \(10, 12, 3\)
2) \(4, 4, 10\)
3) \(5, 6, 11\)
4) \(8, 9, 10\)
Note: 1 and 4 work. Why don’t the sides with lengths in 2 and 3 work? Can you come up with a general rule?
