Intersection of two triangles
Posted:
Nov 5, 2012 9:33 PM



If we assume that s1(x)=s2(x) (the areas of the two triangles are equal) and and we know (x1, y1), (x2, y2), (x3, y3)and also we assume that the line L which is between (x1, y1) and (x4, y4), because we know for example another point in this line so we know the slope and the line. How can I find x4 ? At fisrt , I want to find(x(x4), y(x4)) (intersection of two triangles) , so we have: (y2y1/x2x1)(xx1) + y1 = (y3y4/x3x4)(xx3)+ y3 then we should solve this equation to find x and y in terms of x4. Then by equality of areas of two triangles chould we find x4? could some body help me to find x4 for me?
