1.   In which figure is a median and an angle bisector of
and is an altitude?
    A. B.
    C. D.
    Hint

  2.   Refer to the figure. Is longer than Explain.
   
    A. All of these.
    B. Yes; is the hypotenuse of and is a leg.
    C. Yes; the measure of the angle opposite is 90 and the measure of the angle opposite must be less than 90 because the sum of the measures of the angles must be 180.
    D. Yes; the shortest distance from a point to a line is a perpendicular segment.
    Hint

  3.   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. 2 and 5
    C. 1 and 3 D. 1 and 7
    Hint

  4.   Write an inequality to describe the possible values of x.
   
    A. x > 17 B. x > 20
    C. x < 17 D. x < 20
    Hint

  5.   CPR has vertices C(15, 1), P(9, 11), and R(2, 1). Determine the coordinates of point A on so that is a median of CPR.
    A. B.
    C. D. (12, 6)
    Hint

  6.   Name the property that justifies that if a is less than b, then a cannot be greater than b.
    A. Multiplication Property B. Transitive Property
    C. Subtraction Property D. Comparison Property
    Hint

  7.   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. 10 and 35
    C. 5 and 35 D. 10 and 25
    Hint

  8.   What is the relationship between AM and BM?
   
    A. AM > BM B. It cannot be determined with the information given.
    C. AM < BM D. AM = BM
    Hint

  9.   State the assumption that could be used to start an indirect proof of the statement m1 + m2 = 180.
    A. m1 + m2 180 B. m1 and m2 are supplementary.
    C. m1 and m2 are complementary. D. m1 + m2 = 90
    Hint

  10.   State the assumption that could be used to start an indirect proof of the statement AB + BC > DE.
    A. AB + BCDE B. AB + BC = DE
    C. AB + BCDE D. AB + BC < DE
    Hint
