CIRCLE GEOMETRY 1
, IMPORTANT TERMINOLOGY
Arc -An arc is a part of the circumference of a circle
Chord- A chord is a straight line joining the ends of an arc.
Radius- A radius is any straight line from the centre of the circle to a point
on the
circumference
Diameter -A diameter is a special chord that passes through the centre of
the circle. A
Diameter is the length of a straight line segment from one point on the
circumference to another point on the circumference, that passes through
the centre of the circle.
Segment- A segment is the part of the circle that is cut off by a chord. A
chord divides a
circle into two segments
Tangent- A tangent is a line that makes contact with a circle at one point on
the
circumference (AB is a tangent to the circle at point P).
