  • vertical angles
  • straight angle
  • parallel
  • perpendicular
  • perpendicular bisector
  • circle
  • converse
  • inverse

  • SSS Congruence
  • ASA Congruence
  • AAS Congruence
  • CPCPC – Corresponding Parts of Congruent Polygons are Congruent
  • Vertical Angle Theorem (VAT)
  • BAIT – Base Angles of an Isosceles Triangle are congruent.
  • Converse of BAIT – if two angles of a triangle are congruent, then the sides opposite them are congruent (the triangle is isosceles).

 

Division 2:

    • Read the following sections of p. 176:
      • Basic Ideas
      • Postulates
      • Theorems
      • Constructions
    • Do #4-9 on p. 177
    • Do #51, 52 from p. 180 in Jacobs.  Please make sure you
      • Copy and mark up the diagrams
      • Use the 3-column format
      • Rely only on postulates and congruence theorems we’ve discussed, not on any intuitive or physical arguments (though those can certainly help with your understanding of why what you are being asked to prove is true)
    • Read pp. 212-213 and take notes. 

Division 3:

    • Read and takes notes on the following sections of p. 176:
      • Basic Ideas

      • Theorems
      • Constructions

Mon.,

Dec. 15

Division 2:

  • This weekend is a chance for you to catch up -- those of you who have outstanding work, that is.  If you have missed assignments or a large yellow "Redo" on the front of your triangle congruence handout from 12/05, please bring it in on Monday.   

Division 3:

  • Do problems 51 and 52 on p. 180 in Jacobs.  Do the full-on proof thang -- make sure that you redraw and mark up the diagrams, have three columns filled with statements, reasons, and premises, and that you EMAIL ME with any questions over the weekend.

Fri.,

Dec. 12

Division 2:

  • In Jacobs, read pp. 163-4, again.  Do all of Set I and all of Set II, from pp. 165-7.

Division 3:

  • Read pp. 169-171 and be ready to explain in class, at the board, why each of constructions 1-5 "works". That is, you should know why each of the constructions produces what it's supposed to.  For instance, you should be able to prove, using only your notes (not the book!), why, if you copy a triangle by the method outlined in Construction 5, the resulting two triangles will indeed be exact copies of one another (i.e., congruent).  If you would like to refresh your memory on Constructions 1 and 2, see p. 25 in Jacobs. 
  • If you did not complete the December 2nd assignment in full, please bring a finished verison of that homework to class.

Thur.,

Dec. 11

Division 2 and 3: Toxins book, p.46. Please answer all questions.

Also, draw the Lewis structures for the following molecules: H2O2, SiO2, MgCl2, HCN and H2C2. (the numbers should be subscript, but the web page doesn't let me do it)

Tues.,

Dec. 9

Division 2:

  • Linkage problem, given in class Monday, December 8th
  • Read pp. 163-4 in Jacobs.  This is SSS, which we have discussed but not proved in class.  Bring in 1+ pages of GOOD notes (no fragments of sentences, no pronouns without antecedents) on the proof.  Don't worry so much about the details -- concentrate on the skeleton, the basic structure.  It's OK not to understand it the first time, and it's OK to read slowly and in several sittings.  Don't give up!


Division 3:

  • Read pp. 163-4, and write a summary of the proof of Theorem 11 (from p. 164).  This is our first real, tough, multi-step proof, and we expect this to be challenging.  Spend mulitple days chewing the proof over, piece by piece.  Chew it thoroughly!  It's OK if it's frustrating at first, and it's OK if your summary isn't "perfect".  The important thing is to understand what logical steps lead us from our givens to our conclusion.

Words to learn: solution, homogeneous, heterogeneous, mixture, solvent, solute, filtrate, sediment, hydrocarbon, polar, apolar, extraction, yield

Do the following problems:

1) You have re-crystallized 300 g of copper sulfate. After disolving the salt in hot water, you let the solution cool down again and wait for crystals to grow. Aftrewards you filter the mixture and try the sediment. You end up with 240 g. What was the yield of the recrystallization?

2) You have come up with a molecule that acts as a cure for cancer. Your yield for the complete purification is typically 27%. How much do you have to start with if you want to end up with 210 g of purified compound?

3) So far we have learned about filtration and extraction. If you have a homogeneous solution, which one of the two would you use to purify the different components of the mixture?

Distinction: 4) Based on what you have learned about molecules as slovents, which of the following molecules would make a polar solvent and which would make an apolar solvent. Give the reasoning behind your answers!

    • Experiment with circles to find the reflected point.  Don’t give up!
    • Check your answer by moving the original point (called the preimage) around – does the entire setup (line, reflected point, and all) move with it?

From Maya (note that all of this work is to turn in!):

  • Do the reading from the Howard Eves book, except for the parts I told you could be omitted.  Just some vocabulary notes -- on p. 43, integral number means "whole number", and on p. 44, in the footnote, unity means "one".  Your assignment, apart from reading these few pages, is to write a one-sentence summary of each paragraph.  I know this is a challenging text to read, so please feel free to email me with questions/talk to me during SREPTs about it. 
  • Prove the Lemma from class: If a is a whole number, and a^2 is even , then a is even.  Use the formal definitions of even and odd!
  • Write a paragraph about why the angle bisector construction we did in class on Tuesday actually splits the original angle in half.  No arguments based on measurement or eyeballing!

Post-quest Practice (click here for a more easily printable copy of this):

  • Vocabulary (first score): If you got less than 8 (or 7 11/12ths) on the vocabulary section, go to the glossary section at the end of the textbook and make new flash cards using the exact wording for (those in italics are not in the glossary):
    • acute, angle, circle, collinear, complementary angles, concurrent, conjecture, contrapositive, converse, converse error, coplanar, corollary, deductive reasoning, inductive reasoning, inverse, inverse error, non-collinear, obtuse, opposite rays, parallel lines, perpendicular lines, postulate, proof, rectangle, right angle, square, straight angle, supplementary angles, theorem, transversal, vertical angles.
  • Logic (second score): If you got less than 5 on this section, do this problem (actively look to avoid making converse and inverse errors and to see if the contrapositive of a statement is informative). If you got less than all six, this is also still worthwhile practice. Make a diagram showing the links that you claim. Do not make claims based on anything but what is stated here.
      1. Elizabeth is a Queen
      2. If you are royalty then you have a furry jacket.
      3. If you are a commoner, you do not get to live in a castle.
      4. If you live in a castle, then you have a stone hearth.
      5. If you do not have a furry jacket, then you are cold in the winter.
      6. If you ignore the pleas of the commoners, then you have a stone heart.
      7. If you are a queen, then you are royalty.
      8. If your husband is the king, then you are the queen.
      9. If you are a queen, then you get to live in a castle.
    • For each of the following answer True, False, or Can't be determined from the given information:
      • Elizabeth is royalty.
