2. CN = _____ = CD 2 = _____ cm 2. Def. of midpoint

3. MN = MB + ______ + CN 3. ____________________

4. MN = ________ cm 4. Algebra

Answers

  1. Answer:
    The distance between of the AM = BM = AB/2  is 3 cm, NC = ND = DC is 3 cm, MN = MB + DC + NC, and MN is 6.
    1. AM = BM = AB/2 = 3 cm.
    2. NC = ND = DC = 3 cm.
    3. MN = MB + DC + NC.
    4. MN = MB + DC + NC = 3 + 6 + 3 = 12 cm.
    Step-by-step explanation:
    Using coordinate geometry, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.
    Then we know
    AM=MB
    NC=ND
    Then we have
    AM+MB=AB
    AM+AM=6
    Similarly, we have
    NC = ND = 3 cm
    AM = MB = 3 cm
