5.5 (McDougal Littell Geometry) Triangle Inequality Theorem

Given a side length "c" of 10, experiment with various lengths for sides a and b using sliders. What values form a triangle and which do not? What is characteristic of those that do and do not?

If you have not noticed, a triangle can only be formed when a+b>c.
