Question: quadrilateral abcd is an isosceles trapezoid with?
Answer: SOLUTION: Quadrilateral ABCD is an isosceles trapezoid with AB parallel to DC, AC=DC, and AD=BC. If the height h of the trapezoid is equal to AB, find the ratio AB:DC. I used coordinate geometry to solve the problem; there are certain to be other paths, possibly much easier.... Let points C and D be C(0,0) and D(1,0).
