1 Circles Circles and Basic Terminology I. Circle  the set of all points in a plane that are a given distance from a given point (called the center) in the plane. Circles are named by their center. II. Radius  a segment with one endpoint the center of a circle and the other endpoint on the circle. III. Circumference  the length of the perimeter of a circle; the distance around a circle. IV. Chord  a segment that joins two points on a circle. V. Diameter  a chord that passes through the center of the circle. The diameter of a given circle is twice the length of its radius. VI. Secant  a line that contains a chord of a circle. VII. Tangent  a line in the plane of a circle that intersects the circle in exactly one point (called "the point of tangency"). VIII. Congruent circles  circles that have congruent radii. IX. Concentric circles  two circles in the same plane with the same center but different radii.
2 X. Inscribed polygon  a polygon whose vertices are on the circle XI. Circumscribed polygon  a polygon whose sides are tangent to a circle. XII. Sphere  the set of all points in space a given distance from a point called the center of the sphere. The given distance is called the radius of the sphere. Properties of Tangents I. Definitions  A. Common tangent  a line that is tangent to two coplanar circles. 1. common external tangent  does not intersect the segment joining the centers of the two circles. 2. common internal tangent  does intersect the segment joining the centers
3 of the two circles. B. Externally tangent circles  if each circle lies in the exterior of the other. C. Internally tangent circles  if one circle lies in the interior of the other. II. Theorem  If a line is tangent to a circle, then it is perpendicular to the radius at the point of tangency. III. Theorem  Converse of Theo IV. Theorem  If two segments from a common exterior point are tangent to a circle, then they are congruent.
4 V. Corollary  the line through an external point and the center of a circle bisects the angle formed by the two tangents from the external point. VI. Examples  A. Example #1: B. Example #2:
5 Angles and Arcs I. Definitions  A. Central angle  an angle whose vertex contains the center of a circle. B. Arc  consists of two points and a continuous part of the circle that lies between them. 1. major arc  an arc in the exterior of the central angle; by convention, denoted by three letters (e.g., ACB). <2. minoir arc  an arc which includes the cebtral angle; by convention, denoted by two letters (e.g., AC). C. Sum of Central Angles  the sum of the measures of the central angles of a
6 circle with no interior points in common is 360 degrees. D. Semicircle  the congruent arcs formed when the diameter of a circle divides the circle into two congruent arcs. II. Postulate  the measure of adjacent, nonoverlapping arcs is the sum of the measures of the two arcs. That is, III. Arc Measure versus Arc Length  Arc Measure major arc: 360 degrees  the degree measure of its central angle minor arc: the degree measure of the central angle Arc Length the length of the circumference proportional to the measure of the central angle when compared to the entire circle. IV. Theorem  In the same or in congruent circles, two arcs are congruent IFF their central angles are congruent. Arcs and Chords I. Arc of a chord  when a minor arc and a chord have the same endpoints. II. Theorem  In a circle or congruent circles, two minor arcs are congruent IFF their corresponding chords are congruent.
7 III. Theorem  In a circle, if a diameter is perpendicular to a chord, then the diameter bisects the chord and its major and minor arcs. <> IV. Theorem In a circle, if a diameter bisects a chords and its arcs, then it is perpendicular to the chord V. Theorem  If a chord is a perpendicular bisector of another chord, then it is a diameter. VI. Theorem  In a circle or congruent circles, two chords are congruent if they are equidistant from the center. VII. Theorem In a circle or congruent circles, if two chords are equidistant form the center they are congruent VIII. Example: Sec Inscribed Angles I. Definitions  A. Inscribed angle  An angle with vertex on a circle and sids that contain chords of the circle.
8 B. Tangentchord angle  an angle with vertex on a circle; one side tangent to the circle at the vertex and the other side containing a chord. II. Theorem  the measure of an inscribed angle is equal to onehalf the measure of its intercepted arc. A. Example: III. Theorem  If two inscribed angles of a circle or congruent circles intercept the same or congruent arcs, then the angles are congruent. IV. Theorem  An angle inscribed in a semicircle is a right angle; if an inscribed angle is a right angle, its intercepted arc is a semicircle (and has degree measure of 180.) V. Theorem  If a quadrilateral is inscribed in a circle, then its opposite angles are supplementary. VI. Example
9 Angles of Chords, Secants and Tangents I. Theorem  The measure of a tangentchord angle is onehalf the measure of its intercepted arc. <> II. Theorem  The measure of an angle formed by two chords intersecting in the interior of a circle is onehalf the sum of the intercepted arcs. A. Example: III. Theorem  The measure of an angle formed by two secants, two tangents, or a secant and a tangent (drawn from a point on the exterior of a circle) is equal to the difference of the measures of the intercepted arcs.
10 IV. Examples  A. Example #1: B. Example #2: Extension  Special Segments in a Circle I. Theorem  If two chords intersect in a circle, then the product of the lengths of the segments of one chord equals the product of the lengths of the segments of the second chord.
11 A. Example: II. Theorem  If two secant segments are drawn to a circle from an exterior point, then the product of the lengths of one secant segment and its external segment equals the product of the lengths of the other secant segment and its external segment. A. Example: III. Theorem  If a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the length of the tangent segment equals the product of the lengths of the secant segment and is external segment. A. Example:
12 IV. Circle/Segment Proof  Equations of Circles I. In the coordinate plane, the equation of a circle with center (h, k) and radius "r" can be obtained by using the distance formula. Consider the circle below with center at the origin and a radius of 6 units:
13 Now consider a circle with center at (2, 3) and radius of 6 units: This leads to the following which gives an equation of a circle that has its center at (h, k) and radius of "r" units. II. Examples A. Example #1: B. Example #2:
