Chord
A segment whose endpoints are on the circle
Diameter

Radius
A segment whose endpoints consist of the center of the circle and a point on the circle
Tangent
If a line intersects a circle at exactly 1 point, then the line is a tangent of a circle
Secant
If a line intersects a circle at two points, then the line is a secant of the circle
Common tangent
A line that is tangent to two circles
Common external tangent
A common tangent that does not intersect the segment that joins the centers of the circles
Common internal tangent
A common tangent that intersects the segment that joins the centers of the circles
Tangent circles
Circles that have exactly one point of intersection
Concentric circles
Circles that have the same center
Congruent circles
Circles with congruent radii or diameters
Circle
Set of all points in a plane that are equidistant from a given point called the center
