WebAs you can see from the video, the intersection point is near to the point ( (a+b)/2, c/2). That would mean that that point weighs 2 times than point (0, 0). Let's focus on the x-coordinate first. Since we know that (a+b)/2 weighs two more than 0 then the weighted average of the x-coordinate would be: ( (a+b)/2 + (a+b)/2 + 0) / 3 WebMar 11, 2016 · Tutorial showing how to approach a geometric proof using vectors.
