Step-by-step explanation:
A circle is the locus of a point which moves in a plane in such a way that its distance from a given fixed point is always constant.
A line segment joining the centre and a point on the radius is called its radius. The plural form of radius is radii.
The fixed point from which the circle is made is called its centre.
A diameter is a chord of a circle passing through the centre of the circle. A diameter is the longest chord of a circle
A chord of a circle is a line segment joining any two points on the circle.
Circle
A circle is a round shaped figure that has no corners or edges. In geometry, a circle can be defined as a closed, two-dimensional curved shape.
Radius
The distance from the center to the circumference of a circle. It is half of the circle's diameter.
Centre
In geometry, a centre of an object is a point in some sense in the middle of the object.
Diameter
In geometry, a diameter of a circle is any straight line segment that passes through the centre of the circle and whose endpoints lie on the circle. It can also be defined as the longest chord of the circle.
Chord
In plane geometry, a chord is the line segment joining two points on a curve. The term is often used to describe a line segment whose ends lie on a circle.
