  • The set of points in a plane equidistant form a given point(the center of the circle).
    Circle
  • Circle:
    • Set of points in a plane equidistant from a given point (the center of the circle)
  • Radius:
    • Segment from the center of the circle to a point on the circle (distance from the center to a point on the circle)
  • Circumference:
    • Distance around the edge of the circle
  • Congruent Circles:
    • Two circles with the same radius
  • Diameter:
    • Segment that goes through the center of the circle, with both endpoints on the edge of the circle
  • Chord:
    • Line segment that goes from one point to another on the circle's circumference
  • Tangent:
    • Line that intersects a circle at only one point
    • Radius at the point of tangency is perpendicular to the tangent line
  • Secant:
    • Line that intersects a circle at two points
  • Inscribed Angle:
    • Angle made from points sitting on the circle's edge
    • A and C are "end points", B is the "apex point"
  • Central angle:
    • Angle with vertex at the center of the circle
  • Arc:
    • Part of the circumference (edge) of the circle
    • Measure of an arc is equal to the measure of the central angle formed by its endpoints
    • Arcs are named by their endpoints
  • Minor arc:
    • Arc whose measure is less than 180 degrees
  • Major arc:
    • Arc whose measure is greater than 180 degrees
  • Semicircle arc:
    • Arc whose measure is 180 degrees
  • Chord Central Angles Theorem:
    • If two chords in a circle are congruent, they determine two central angles that are congruent
  • Chord Arcs Theorem:
    • If two chords in a circle are congruent, their intercepted arcs are congruent
  • Perpendicular to a Chord Theorem:
    • Perpendicular from the center of a circle to a chord is the bisector of the chord
  • Chord Distance to Center Theorem:
    • Two congruent chords in a circle are equidistant from the center of the circle
  • Perpendicular Bisector of a Chord Theorem:
    • Perpendicular bisector of a chord passes through the center of the circle
  • Tangent Theorem:
    • A tangent to a circle is perpendicular to the radius drawn to the point of tangency
  • Tangent Segments Theorem:
    • Tangent segments to a circle from a point outside the circle are congruent
  • Inscribed Angle Theorem:
    • Measure of an angle inscribed in a circle is one-half the measure of the central angle
  • Inscribed Angles Intercepting Arcs Theorem:
    • Inscribed angles that intercept the same arc are congruent
  • Angles Inscribed in a Semicircle Theorem:
    • Angles inscribed in a semicircle are right angles
  • Cyclic Quadrilateral Theorem:
    • Opposite angles of a cyclic quadrilateral are supplementary
  • Parallel Lines Intercepted Arcs Theorem:
    • Parallel lines intercept congruent arcs on a circle
