-6. Define the following terms related to a circle and
illustrate them with the help of a figure.
a. Diameter
b. Segment
c. Chord
d. Sector
e. Circumference
f. Concentric circles
Answers
Answer:
Diameter = The chord of a circle passing through its center is called a Diameter.
Segment = A chord of a circle that divides it's circular region into two parts. It's each part is called a Segment.
Chord = A line segment joining any two points of a circle is called a Chord.
Sector = The part of the circular region of the plane enclosed by an arc of a circle and it's two bounding radius is called a Sector of the circle.
Circumference = The whole arc of the circle is called the Circumference of the circle.
Concentric Circle = Concentric circles are circles with a common center. The region between two concentric circles of different radii is called an annulus. Any two circles can be made concentric by inversion by picking the inversion center as one of the limiting points.
