Question

Definition of a circle

Answer 1

1. The Definition of a circle according to a dictionary

2. Definition according to me

3. Examples of circles

Explanation:

1. A round plane figure whose boundary (the circumference) consists of points equidistant from a fixed point (the center).

2. A 2d object with no straight sides and infinite lines of symmetry

3. The shape of a full pie chart, the shape of a pizza, and the shape of the sun in a 2d drawing without rays.

Answer 2

a circle is a simple closed curve all point of which are at the same distance from the given point

circle is the most common geometrical shape and always remained as the round shape

PART OF CIRCLE

CENTER

the fixed point in the plane which is equisdistant from each point on circle is called centre of circle

RADIUS

distance of any point on the boundary of the circle from its Centre it's same and called radius of the circle

DIAMETER

Accord that passes through the centre of a circle is called diameter of the circle

CHORD

line segment joining any two points on the circle is called chord of the circle

ARC

the part of the circle between any two points is called arc of the circle

SEMICIRCLE

the end of point any diameter of a circle divide the circle into two equal are its such Arc is called semi circle

CIRCUMFERENCE

the distance around the circle is called circumference of a circle

SEGMENT

any chord of a circle divides the circular region into part and each part is called segment of circle
