Orthodontist, If a line connects the midpoint of AB and the midpoint of CD than extention of this line will not generally pass the intersection point R of AD and BC. Such midpoint-midpoint line is still a sweeping line according to my definition of a sweeping line: AB:DC=AP:DQ (Nothing...

I can now EDIT the Definition: Edited Definition: If any line INTERSECTS the oppozite sides of a Qudrilateral A, B, C, D in points P and Q in such a manner the ratio AB:DC=AP:DQ holds than this line is called a Sweeping Line.

I got some progress here... Definition: If any line bisects the oppozite sides of a Qudrilateral A, B, C, D in points P and Q in such a manner the ratio AB:DC=AP:DQ holds than this line is called a Sweeping Line. Theorem by Milan Anthony Vlasak: "There is only one Parabola which is...

Sorry guys, I thought it would be easy, but it is not. I have a random quadrilateral A,B,C,D, drawn and a random point M inside of it. Now, I want to draw a line passing through the point M and crossing the sides AB and DC at points P and Q. So far so good, but I want more, in addition...
