IF YOU ARE IN 0B LOOKING FOR HOMEWORK DUE FRIDAY, PLEASE SCROLL DOWN TO PREVIOUS POST!!!
We had a quiz in class today worth 22 pts.
The unit test over Triangles, Congruence, and Deductive Reasoning is after the break: Wed-Thurs, Dec 4-5.
Finals begin Dec 17. Our final is comprehensive for the entire semester. Topic lists/study guides and assignments will be passed out on December 10-11.
Today in class we practiced applying skills from C-17-23. You need to get all of these written up in your Geometric Truth. They are attached to previous posts if you scroll down.
We checked HW #8 and the warm-up.
And then we worked on investigating, questioning, discussing, sketching Triangle Congruence Shortcuts SSS, SAS, ASA, and SAA.
We learned that SSA and AAA combinations do not work.
Shortcuts are guarantees that all corresponding sides and angles will be congruent (all 6 parts of a triangle) if only three parts are congruent. We examined all possibilities and determined that these 4 work.
HW #9 - pp 230-231: 1-2, 4-10, 12-19. Four of these can be answered as "cannot be determined". On 18-19, you may use rigid transformations to say why the figures are congruent.
Write out congruence statements for most problems (state which triangles are congruent and why).
Write up C-24-25 from pp 228-9, using sketches from p 227. The fill in the blank should be obvious.
The online textbook can be very helpful in this chapter.
