I'm interested in finding the equation for the radius (and optionally the center point) for a circle that is tangent to two lines and passing through a specific point on one of the lines. So far, I've found this tutorial showing the circle tangent to 2 lines and another circle.
I tried putting all those formulas in excel and making the circle have a radius of 0 for the point on a line, but it wasn't working as expected. Any help would be appreciated. Thanks!
