C is any point on the line AB, M is the midpoint of AC, and N is the midpoint of ab. if BC = 10cm, then the length of the line Mn is A M C N B _________________________ infer
Let AB = a, then AC = A-10. Na = NB = A / 2. Cm = (A-10) / 2. If point C is n or between an, then CN = bc-nb = 10-A / 2. So, Mn = cm + CN = (A-10) / 2 + (10-A / 2) = 5cm. If point C is n or between BN, then CN = nb-bc = 2 / A-10. So, Mn = cm-cn = (A-10) / 2 - (2 / A-10) = 5cm. Note: let AB = a
