We continued our work with triangle proofs today by taking a look at how congruent triangles can be used to prove other things. The concept of CPCTC was introduced and we went through a few more proofs together in order to see how triangle proofs are used to gain extra information about a drawing. The students then got started on their assignment.
Assignment: section 4-3; page 130-131; WE #1-9 all
