Directions: Adjust the side lengths accordingly, then move the blue points to try and create a triangle.
1) Make a = 5, b = 7, c = 4. Can you create a triangle with these lengths?
2) Make a = 3, b = 7, c = 3. Can you create a triangle with these lengths?
3) Make a = 3, b = 7, c = 4. Can you create a triangle with these lengths?
