Find the tangent point

[Steve]

If this is not the right ng I'm sorry please re-direct me, if it is then,
I'm writing a computer app that has a form that finds the X and Y of the
intersection of two crossed lines.I am also finding the X/Y of the centre
and the tangent points of a circle touching two of the lines,
I know how to find the intersect, but I don't know if there is a formula for
the centre points or tangent points. What I'm doing now is to find the angle
of the lines,using right triangle trig. , then more parts of a right
triangle using the angle of the line and the radius of the circle, then
polar points using the data just calculated, same for the tangents points
using polar from the centre of the circle, as there are four quadrants with
two lines crossing this gets cluttered, Is there a simpler way than breaking
everything down into lots of little right triangles.
thanks

I'm finding this very hard to follow. Please post again, and write
straightforward sentences that an idiot could follow well enough to draw a
picture of your setup, and then tell me what you know and what you're trying to
find.

Thanks,
