Draw a line connecting the midpoints of the two non-parallel edges. Find the mid point of this line. Now draw a vertical line through this point.Dividing it by a parallel line is a bit tricky. The length of this line is the RMS value of a & b - which is SQR{(a^2+b^2)/2}This line can be geometrically constructed and it's said that the ancient Babylonians knew the trick.PS: At least you are still working on the problem... Thanks!!!</blockquote>
