Summary

Why tell a kid the rules of a triangle when they can discover them!?

  1. Students try to create the biggest possible angle inside of a triangle.
  2. They look for triangles with one or more right angles.
  3. Then they add up three angles, trying to find the largest and smallest sums possible.
  4. Students try to create triangles with two and three congruent angles.
  5. We close by posing the question: how are angles and sides related? (Larger/smaller angles mean longer/shorter sides. Same sized angles? Same size sides. )
