listen...........join the top left vertice of trapezium with mid point of the diagonal from bottom left to top right.....!!!!!!!got it..... shall i continue fuether?????

i get the parallel thing, i don't get the how the length = half the difference of the bases. i keep getting half the SUM of the bases... and this is coordinate geom. btw like trap. vertices are (a,0), (0,0), (d,c), and (b,c)
