as level maths coordinate geometry question

Say you have a circle with a tangent. The line passing through the centre or the radius line, will be perpendicular to the tangent, will they only intersect at the point at which the tangent meets the circle?
eg, tangent at (2,1), the perpendicular line and tangent would also intersect at (2,1)?

Yes (if I'm understanding your question correctly).
