Let $\overline T$ be a line crossing the point $P.$ Let $P'$ be some other point on the 2d plane. Find the equation for the circle that passes through $P, P',$ and is tangent to $\overline T.$

Or just find $\Delta \theta.$ I need this for robotics (for positional driving and stuff)

It seems like this is only a part of a question.

I know that the gradient of T' is  tan(theta)

so I know that the gradient of OP is  -cot(theta)

Which points are fixed?

Can you describe the situation better please?
