As shown in the figure, C is the point on the line AB, M is the midpoint of AC, n is the midpoint of BC, e is the midpoint of AB, Mn = 5, CE = 1 The length of AB and en

As shown in the figure, C is the point on the line AB, M is the midpoint of AC, n is the midpoint of BC, e is the midpoint of AB, Mn = 5, CE = 1 The length of AB and en

∵ m is the midpoint of AC, n is the midpoint of BC ∵ Mn = cm + CN = 1 / 2Ac + 1 / 2BC = 1 / 2Ab ∵ AB = 2Mn = 10 ∵ e is the midpoint of ab ∵ AE = 1 / 2Ab = 5 (1) C on the left of e AC = ae-ce = 5-1 = 4 ∵ BC = AB-AC = 10-4 = 6 ∵ CN = 1 / 2BC = 3 ∵ en = cn-ce = 3-1 = 2 (2) C on the right of e AC = AE + CE = 5 + 1 = 6 ∵ BC = AB-A
