Determine with reasons the value of y(XY) in the diagram below. Given that AB= 4 units and BC= 3 units. X and Y are midpoints of AB and BC respectively.

Answer 1

Please describe diagram or post a link.

If ABC form a triangle, and X,Y are mid-points of AB and BC, then mXY = mAC÷2
Reason: ΔBXY~ΔBAC SAS
mXY=mAC÷2 corr. sides proportional
