Geometric Solutions for 2D Intersections
Posted:
Jun 25, 2007 8:59 AM


Greetings,
Perhaps I use "geometric" as an incorrect synonym for "visual", however I am looking for solutions that can be constructed using ruler/ compass and are visually apparent on paper.
The intersection of two straight, infinite lines is a 2x2 linear system that can be solved algebraically  but is there a visual solution?
I think the main problem is visualizing ratio's. It is not apparent that one distance is proportionate to another  simply by observation.
I have also messed with linecircle intersection for years, but I think there must only be an algebraic solution.
Any thoughts appreciated.
