p. 32: 14-24

14-17: Go back to the definitions and examples in your notes, or use the examples in the book on page 28.  Remember for linear pair, they have to be adjacent and their noncommon sides have to form a straight line.

18-21: Look in your notes or book for what complement and supplement mean! (Be careful of the difference between “equals 180” and “add up to 180”)

22: “An angle’s measure”- do you know what it is?  If you don’t know the value of something, assign it a variable!  Whatever that variable is, what expression would represent its complement?  Now, “An angle’s measure” (your variable) “is” (equals) “3 times its complement” (3•”the expression for its complement”).  Then solve the equation and complete the problem.

23: I would copy the diagram into my book so I could physically label the congruent angles and mark the angle measures that were given and that I know!

24: Copy the diagram into your notes, but only two lines at a time, for example, only use lines PR and QS at first, and find their vertical angles.  Then continue that with the other combinations.
