1.   The _______________ states that the sum of the lengths of any two sides of a triangle is greater than the length of the third side.
    A. Triangle Equality Theorem B. Definition of an Inequality
    C. Definition of a Triangle D. Triangle Inequality Theorem
    Hint

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

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

  4.   If 15 and 20 are the lengths of two sides of a triangle, between what two numbers must the measure of the third side fall?
    A. 15 and 20 B. 5 and 35
    C. 10 and 35 D. 10 and 25
    Hint

  5.   Ed has a piece of rope with exactly 10 knots tied to make 9 equal lengths as shown. Using the rope, he wants to use the entire rope to make a triangle so that each vertex of the triangle occurs at a knot. How many different triangles can Ed make?
   
    A. 5 B. 3
    C. 4 D. 2
