Assignment for Friday, March 28, 2008

Due Monday, 3/31/08

Today’s assignment is worksheet 10.4 Practice B.

On Monday we will look at Lesson 10.5, so if you are bored this weekend, you may want to look ahead at all the exciting new theorems that I think you should know.

Here are the answers to the quiz:

1. By the converse of the Pythagorean Theorem, 10²  + 24² = 26² , so AB is perpendicular to CB, so YES, AB is tangent to circle C.

2. NO. Don’t trust the diagram! The segment BC looks like the hypotenuse of right triangle, but the hypotenuse of this triangle is the supposed tangent segment. Since 5²  + 13²  is not equal to 12² , angle CAB is not a right angle.

3. 100°

4. 80°

5. 260°

6. 180°

7. 3

8. 7

Assignment for Tuesday, March 18, 2008

Due Wednesday, 3/19/08

Indirect Proofs worksheet:  do all three proofs.

Correction:  you cannot do the third proof, as you may have already noticed, because if you try it you get to a SSA situation, which we all know is not sufficient information to prove triangles are congruent.  Mr. Weissburg apologizes profusely for his error, but it allows us to use the corrected version as classwork tomorrow.  Use your spare homework time to study vocabulary and concepts for Thursday’s test.
