hello, can some one please explain the example i have attached in detail for each of the steps.
thanks much.
i) AM = OM - OA
MB = OB - OM.
Since AM = MB,
OM - OA = OB - OM.
So.
2OM = OA + OB
Or
OM = (a+b)/2.
ii) MD = OD - OM.....(1)
DC = OC - OD = 2MD
MD = OC/2 - OD/2..(2)
Equate (1) and (2)
OD - OM = OC/2 - OD/2
OD+OD/2 = OM + OC/2
3OD/2 = (a+b)/2 + c/2
OD = (a+b+c)/3
