You would need further information. You earlier posted a problem where you were given the three equations below. 1. 3x  7y  25=0 (equation of AC) 2. 7x + 3y  10 = 0 (equation of BD) 3. 2x + 5y  7 = 0 (equation of CD) Those equations can be solved in pairs to find the coordinates of the points of intersection of the lines AC, BD and CD. For your current question, what further information are you given?
