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

  2.   Marty has a piece of rope with exactly 7 knots tied at equal intervals as shown. Using the rope, he wants to make triangles so that each vertex of the triangle occurs at a knot. How many different triangles can Marty make?
   
    A. 3 B. 4
    C. 2 D. 1
    Hint

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

  4.   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. 28 and 49 B. 10 and 60
    C. 31 and 67 D. 21 and 77
    Hint

  5.   Is it possible to draw a triangle with sides measuring 32, 96, and 118? Explain.
    A. Yes; 96 is between 32 and 118.
    B. No; 32 + 96 is less than 118.
    C. No; 32 is less than 96 + 118.
    D. Yes; the sum of the measures of any two sides is greater than the other side measure.
