Which 3 Line Segments Make a Triangle?
1. Drag vertices or use sliders to change lengths of line segments. Try until you have made two different triangles. Keep track of which DO and which DO NOT make a triangle. Line segments that DO make triangles have this in common: Line segments that DO NOT make triangles have this in common: 2. Make a conjecture: In order to make a triangle... 3. Justify your conjecture using diagrams and what you know about triangles.
