Question

. If B is the mid-point of AC and C is the mid-point of BD, where A, B, C, D lie on a straight line, say why AB = CD?​

Answer 1

Step-by-step explanation:

from this question four points lie on same plane

in which

AB=BC -------1(B is mid point)

BC=CD --------2(C is mid point )

BC is commont

when we put both equation in equally so .Bc is cancelled from both side and we have AB=BC
