12/4/13

Homework: Ch. 6.4 #6, 7, 8, 9, 27, 58, 59

Reminder: Fill out the class evaluation form for this class! 

See this as an opportunity to inform the administration about Mr. Schiffman's general awesomeness and Jedi Mastery of mathematics.

Practice problem 1: Find the midpoints A, B, and C. (see drawing 1)

A = (-1, 9/2)
    To find the x coordinate, add -3 and 1 together and divide by two. To find the y coordinate, add 8 and 1 together and divide by two. You're just finding the average between the two points!

B = (4, 3)

C = (2, -1/2)

Proof practice: Prove that ∆ABC is congruent to ∆XYZ (see drawing 2)
Hint: Remember to use AA.

Practice problem 2: Solve for x (see drawing 3)
     Answer:
                 25/x + 20 = 12/-3x
                 25(-3x) = 12 (x + 20)
                -75x = 12x + 240
                -87x = 240
                 Divide both sides by -87

Line AC ∥ line DQ                       Given
Line ED ∥ line BC                       ∠GEF ≅ ∠CFE, if alternate interior angles are congruent, then the                                                              lines are parallel because the corresponding angles are congruent.
∠FCE ≅ ∠GEA ≅ ∠GDB         Corresponding angles/Alternate interior angles
∠FEG ≅ ∠GBF                          Euclid's postulate #4
Line ED ≅ line CB                       Reflexive argument based upon line AC ∥ line DQ and
