Geometry: Chapter 6

49097 - Circle Terms

QuestionAnswer
chord segment with endpoints on the circle
circle set of points in a plane that are equidistant to a given point
radius segment with one endpoint on center of circle and one endpoint on circle
diameter a chord that passes through the center of the circle
tangent line that intersects the circle at one point
minor arc an arc smaller than a semicircle
semicircle an arc that measures 180 degrees
arc part of a circle
major arc an arc greater than a semicircle
congruent circles circles with the same sized radius
concentric circles non-congruent circles that share the same center
central angle angle that has its vertex at the center of the circle
inscribed circle angle that has its vertex on the circle and its sides are chords
CHORD CENTRAL ANGLES CONJECTURE If two chords in a circle are congruent, then they determine two central angles that are congruent.
CHORD ARCS CONJECTURE If two chords in a circle are congruent, then their intercepted arcs are congruent.
PERPENDICULAR TO A CHORD CONJECTURE The perpendicular from the center of a circle to a chord is the bisector of the chord.
CHORD DISTANCE TO CENTER CONJECTURE Two congruent chords in a circle are equididstant from the center of the circle.
PERPENDICULAR BISECTOR OF A CHORD CONJECTURE The perpendicular bisector of a chord passes through the center of the circle.
TANGENT CONJECTURE A tangent to a circle is perpendicular to the radius drawn to the point of tangency.
TANGENT SEGMENTS CONJECTURE Tangent segments to a circle from a point outside the circle are congruent.
tangent circles circles that are tangent to the same line at the same point
