ABCD is a parallelogram on xy rectangular coordinate plane, three of the four vertices of parallelogram are (5,15) , (5,35) and (-5,15). Which can be the coordinate of fourth vertex?  Choose the correct choice from the following answers:
A) (-5,-5)	B) (5,15)	C) (-5,-35)	D) (-5,10)	E) (15,35)
A(-5, 15)   B(5, 15)   C(5, 35)   X(-5, 35): Parallelogram=Square=AXCB, where AX||CB, AX=CB, XC||AB, XC=AB   Y(-5, 5): Parallelogram=AYBC, where AY||BC, AY=BC, AC||YB, AC=YB   Z(15, 35): Parallelogram=ACZB, where AC||ZB, AC=ZB, CZ||AB, CZ=AB   Ans:(15,35)
