  1. If a quadrilateral is a square, then it has 4 right angles. A quad is a square What is the conclusion? What is p? It has 4 right angles What is the converse? If a quadrilateral has 4 right angles, then it is a square.

  2. If a quadrilateral is a square, then it has 4 right angles. If a quad is not a square, then it does not have 4 right angles What is the contrapositive? What is the inverse? If a quad does not have 4 right angles, then it is not a square. Is the inverse true or false? False, it could be a rectangle.

  3. m  w~r  ~wp m p  r (p  m  w  r) OR ~r  ~p (~r  ~w  ~m  ~p) What conclusion can you draw?

  4. Construct a truth table for (pΛ~q)ᴠr . F F T T F F F F T F T T T F T F F F T T F F T T

  5. Given: Diagram as shown. Prove: angle 1 congruent angle 2 1 2

  6. If an animal is a zebra, then it is mammal. If an animal is NOT a zebra, then it is not a mammal. What is the contrapositive? What is the inverse? If an animal is not a mammal, then it is not a zebra. Is the inverse true or false? False, the mammal could be a human.

  7. If an animal is a zebra, then it is mammal. An animal is a zebra What is q? What is p? It is a mammal What is the converse? If an animal is a mammal, then it is a zebra.

  8. Construct a truth table for (~p ᴠ q)ᴠ~r F T F T F T F T F F F F T T T T T T F F T T T T T T F T T T T T

  9. Given: Diagram as shown. Prove: angle BAT congruent angle CAR B C A R T

  10. r  w~t  ~sa rt  a What conclusion can you draw? s  w (s  t  a  r  w) OR ~w  ~s (~w  ~r  ~a  ~t  ~s)

  11. If an angle measures 100˚, then it is NOT acute. If an angle is not 100˚, then it is acute. What is the contrapositive? What is the inverse? If an angle is acute, then it doesn’t measure 100˚. Is the inverse true or false? False. Counterexample? 150˚ (a 150˚angle is not 100˚, but is also not acute.)

  12. If an angle measures 100˚, then it is NOT acute. An angle measures 100˚ What is the conclusion? What is the hypothesis? It is not acute What is the converse? If an angle is not acute, then it measures 100˚
