Geometry:2-7 & 2-8 (Monday)

First of all, remember there's a test tomorrow! Make sure your notes are up to speed, because you can use them on the test. (for anyone who still hasn't put together their geometry notebook, today is the day!)

Now, the assignment:
1. Read 2-7

2. Back to the SketchUp and the frigate. You can download it here if you don't have it on your computer. Look at the mizzen (rear) mast. If you count the very bottom and very top of the mast, and all the joints in between, there are 5 “points” on the “line” of the mast, which we can call A, B, C, D, and E.

If BC = DE, formally prove that BD = CE.

3. Do problems #4-10 even, 26, 30, 34, 38, and 44

4. Read 2-8

5. Back to the frigate. If the top of the sail behind the mizzen mast is a segment CF, and the measure of angle FCD is 55 degrees, find the measure of angle FCB, justifying each step.

6. Do problems #4-8 even, 12-16 even, 24, 28-34 even, 40, and 44

E.C. Problems 41 & 42, and the following 2 questions:
What theorem from this section helps us solve problem 40?
The snake and the clearwater don't really form supplementary angles, but if they did, the acute angle would measure around 70 degrees. What would the obtuse angle measure?
