Solution
The required figure is shown From figure, BL=DM and BL∥DM and BLMD is a parallelogram, therefore BM∥DL From triangle ABY L is the midpoint of AB and XY∥BY, therefore x is the midpoint of AY .ie AX=XY ..........(1) Similarly for triangle CDX CY=XY ......(2) From (1) and (2) AX=XY=CY and AC+XY+CY Hence proved
