Answer:

Verified: The tangent of any point to a circle is perpendicular to the radius through that point

Step-by-step explanation:

Consider the diagram below.

Given:

The center of the circle is O and AB is a tangent to the circle at point P.

OP and OR are the radii.

To Prove: OP ⊥ AB

Proof:

Extent OR to touch the tangent line AB at Q.

Then, OQ = OR + RQ, i.e. OQ > OR

And OQ > OP

Thus, the length of OP is shorter than any line joining the tangent at any point.

The shortest distance of a point from a given line is perpendicular to that line, i.e. the shortest distance line OP is perpendicular to the tangent line AB.

Hence proved that the the tangent of any point to a circle is perpendicular to the radius through that point.
