We continued our work with congruent triangles today by taking a look at how to work with 2 pairs of triangles. The method that was demonstrated in class was called a "key steps proof" , as we shortened the process of using the givens and reflexive parts of triangles. We went through 3 or 4 together before the students got started on their assignment.
Assignment: section 4-6; page 148-150; WE 1-9, 11, 12
