Diameter - The line segment that is drawn through the center with endpoints on the circle. Chord - A line segment with endpoints on the circle. The diameter is a special chord. Tangent - a line that intersects the circle at only one point called the point of tangency. Secant - a line that intersects the circle at exactly two points.
