We reviewed the idea of how to construct proofs today by having the students try to write a complete 2 column proof on their own. We went over this together as continued practice for the more complete proofs that are coming up in chapter 4.
Our lesson today focused on how to calculate angles in triangles, as well as how to classify triangles according to the length of their sides and the size of their angles. We went over several examples together before the students got started on their assignment.
