I need the steps to working out this proof problem.
GIVEN: LINE PA IS TANGENT TO THE CIRCLE WITH CENTER O; PROVE: TRIANGLE APB ~ TRIANGLE CPA
I'm sorry but that is not enough information to describe the figure.
You'd have to tell us which of A, P, B, and C is at the point of tangency,
or whether some of these points lie on the circle or off the circle.
If you want to, you can try to explain it better in the thank-you note window,
and if I can understand what figure you have, I'll outline a proof of
it right here on this very page, and delete what you see written here.
