(1)__________________ - segment on a secant line with exactly one endpoint on the circle

(2)__________________ - arc having endpoints on the sides of an inscribed angle; arc lies on the interior of the inscribed angle

(3)__________________ - a term describing a polygon where all of the vertices of the polygon lie on the circle; this polygon is inside the circle

(5)__________________ - the single point where a circle and tangent meet

(6)__________________ - angle inside a circle having the vertex on the circle and sides that are chords

(7)__________________ - segment of a tangent line with exactly one endpoint on the circle

(8)__________________ - when two chords intersect inside a circle, each chord is divided into these two lengths

(9)__________________ - circles having the same center

(10)__________________ - set of all points in a plane that are equidistant from a given point

(11)__________________ - half the diameter; this is a segment that with endpoints at the center of the circle and a point on the circle

(12)__________________ - the longest distance between two points on a circle

(13)__________________ - chord that passes through the center of the circle

(14)__________________ - an angle with a vertex on the center of the circle

(15)__________________ - circumference divided by the diameter

(16)__________________ - line that intersects a circle in exactly two points

(17)__________________ - arcs on the same circle that have exactly one point in common

(18)__________________ - portion of a circle defined by two endpoints

(19)__________________ - line that touches a circle in exactly one point

(20)__________________ - a secant segment that lies on the outside of a circle

(21)__________________ - line, ray, or segment that is tangent to two circles

(22)__________________ - a term describing a circle that intersects all of the vertices of a polygon; the circle lies outside the polygon

(23)__________________ - the distance between two endpoints along an arc; measured in linear units

(24)__________________ - the shortest distance between two points on a circle

(25)__________________ - the point inside a circle by which all points on the circle are an equal distance away

(26)__________________ - arcs having the same measure

(27)__________________ - arc with endpoints that lie on the diameter

(28)__________________ - a segment with endpoints on the circle
