Move the vertices of the triangle to discover the relationship between the sizes of angles and the sizes of the sides.
1. Move vertex B until angle B is an obtuse angle. What is the largest side when angle B is an obtuse angle?
2. Move vertex B until angle B is the smallest angle. What is the smallest side when angle B is the smallest angle?
3. Describe in your own words how you can list the sides from smallest to biggest based on the size of the angles.
4. Move vertex A until AB is the longest side. What is the largest angle when AB is the longest side?
5. Move vertex A until AB is the shortest side. What is the smallest angle when AB is the shortest side?
6. Describe in your own words how you can list the angles from smallest to largest based on the size of the sides.
