What is the relationship between a tangent and the radius?

The tangent at a point on a circle is perpendicular to the radius drawn to that point.

What is the tangent length property?

Tangents drawn from the same external point to a circle are equal in length.

When two chords intersect inside a circle, the products of the segments of the two chords are equal.
