tangent segment:	A segment that contains a point of tangency and another point of a tangent line to a circle.
tangent to a circle:	A line that is coplanar with the circle and intersects the circle in exactly one point.
theorem:	A statement that has been proved true.
translation:	A translation in a plane from A to A' is a transformation which maps any point P into a point P' such that PP' = AA' and PP' \|\| AA'.
