Triangle Side Inequality

Author:

The goal is to determine what relationship a, b, and c must have to have it be possible to form a triangle with them. You can drag around the endpoints of segments a and b to try and make them connect. Change the lengths of the segments using the sliders at the top to experiment with different lengths to see when it is possible and when it is impossible to form a triangle with the given lengths.
