concepts

the point where a tangent meets a circle is called the point of contact

a point outside the circle has 2 tangents passing through it

a point on the circle has 1 tangent passing through it

A point inside the circle has no tangents passing through it

A secant is a line that intersects a circle at two distinct points

A tangent is a line that intersects a circle at only one distinct point

theoroms

Theorom 3 = a line drawn through the end of a radius

Theorom 2 = two tangents from a single external point which meet the same circle are equal

Theorom 1 = a tangent which meets the radius of a circle at the point of contact is perpendicular to the radius
