1.   Looking at several specific situations to arrive at an educated guess is called __________.
    A. guessing B. a conjecture
    C. inductive reasoning D. deductive reasoning
    Hint

  2.   In the figure, ABCD is a square. Which of the following is a valid conjecture about points A, B, C, and D?
   
    A. None of the statements are valid conjectures. B. AB = BD
    C. AB + CD = 12 D. AB = CD
    Hint

  3.   Refer to the figure. If G is the midpoint of , which conjecture is true?
   
    A. is exactly 5 feet long.
    B. intersects at exactly two points.
    C.
    D. None of the statements are true.
    Hint

  4.   Determine if the following conjecture is true or false? Explain.

Given: x2 = 4
Conjecture: x = 4 or x = -4

    A. False; the square root of 4 is 2 or -2.
    B. True; two answers are always more accurate than one answer.
    C. False; the square root of a positive number is always a positive number.
    D. True; squaring a positive number results in a positive number and squaring a negative number results in a positive number.
    Hint

  5.   Make a conjecture based on the following information. M is obtuse.

    C. mM = 30 D. mM is not 180
