**In the Investigations 3.1 and 3.2 the focus questions were:**

- What combinations of three side lengths can be used to create a triangle? (Inv 3.1)
- What are the exact number of side length and angle measurements needed to draw an exact copy of a triangle. (Inv 3.2)

Here are some pictures of the kids working with polystrips creating different triangles with different side lengths chosen from a random number generator.

The following are the links to the notes from class as well as the ACE Problems for 3.1 and Inv 3.2 Notes.
