has a large pile of colored rods. Each color is a different length. She is
trying to connect different colored rods to make triangles as part of a hanging
sculpture. Here is a list of rod lengths.
How many triangles can she make with them if each side is a different color?
List the combinations that work.
Karen was just trying different combinations of colored rods one at a time,
placing the colored rods together to see if they make a triangle. What method
did you use to determine the triangle options? Which method do you think is
better and why?
