Find the lengths of the diagonals of this trapezoid. when the given length for the sides are (b,c), (b,c),(a,0), (a,0)

geometry!! 
drwls,
Are those the coordinates of corners or the lengths of sides?
If they are coordinates, two of them are the same, and you do not have a trapezoid. You may have omitted a minus sign.
