1.   Is it possible to draw a triangle with sides measuring 13, 21, and 39? Explain
    A. Yes; the sides of the triangle are not all the same lengths.
    B. No; 13 is less than 21 + 39.
    C. Yes; 13 + 21 is less than 39.
    D. No; 39 is greater than 13 + 21.
    Hint

  2.   If the measures of two sides of a triangle are 3 and 1, between what two numbers must the measure of the third side fall?
    A. 2 and 4 B. 1 and 7
    C. 2 and 5 D. 1 and 3
    Hint

  3.   Refer to the figure. Which statement is never true?
   
    A. If is obtuse, then EG > EF.
    B. If FG = 4, EGDE = 6, then EF < 18.
    C. If DF = 20, FG = 13, and EG = 15, then EF = 11.
    D. If EG = 6, ED = 8, and then FG = DF.
    Hint

  4.   Which of the following could not be a triangle?
    A. 7, 28, 22 B. 7, 11, 3
    C. 9, 9, 9 D. 15, 18, 8
    Hint

  5.   If 28 and 49 are the lengths of two sides of a triangle, between what two numbers must the measure of the third side fall?
    A. 10 and 60 B. 28 and 49
    C. 31 and 67 D. 21 and 77
    Hint
