We continued our work with congruent triangles today by taking a look at how to use triangles to prove various vocab words like midpoint and parallel lines. All three examples we did involved getting triangles congruent first and then using CPCTC to determine the definition of the vocab word.
The students then took their 2nd proof practice quiz.
Assignment: section 4-3; page 129; CE 2, 3, 5 (write a complete 2-column proof); page 126; WE #18
