This section of Revision Maths defines many terms in relation to circles, including: Circumference, Diameter, Radius, Chord, Segment, Tangent, Point of contact, Arc, Angles on major and minor arcs, Angle of Centre and Sectors. Circumference: The circumference of a circle is the distance around it.
A chord is a line segment whose endpoints lie on the circumference of a circle. Continue; A tangent is a line that touches a circle at exactly one point. This is called the point of tangency. Continue; An arc is a section of the circumference of a circle. Continue; A sector is a part of the interior of a circle, bounded by an arc and two radii ...
The chord of a circle is a straight line that connects two points on the circumference of a circle. The longest chord in a circle is the diameter of the circle. The perpendicular from the centre of a circle to a chord bisects the chord (splits the chord into two equal parts). In the diagram above, AB is a chord and CE is a radius.
A chord (from the Latin chorda, meaning "bowstring") of a circle is a straight line segment whose endpoints both lie on a circular arc. If a chord were to be extended infinitely on both directions into a line , the object is a secant line .
chord is a line segment whose endpoints lie on the circumference of a circle. tangent is a line that touches a circle at exactly one point. This is called the point of tangency. sector is a part of the interior of a circle, bounded by an arc and two radii. Finally, a segment a chord.

When a chord of circle is drawn, it divides the circle into two regions, referred to as the segments of the circle: the major segment and the minor segment. A chord when extended infinitely on both sides becomes a secant.
