$\bold{\underline {1) Circle:-}}$A circle is the collection of all those points in a plane whose distance from a fixed point remains constant.

$\bold{\underline {2) Diameter \: of \: a \: circle:-}}$A line segment passing through the center of a circle and having its end points on the circle is called a diameter of the circle.

$\bold{\underline {3)Chord \: of \: a \: circle:-}}$A line segment with its end points lying on s circle is called a chord of the circle.

$\bold{\underline {4)Secant \: of \: a \: Circle:-}}$A line passing through a circle and intersecting the circle at two points is called a secant of the circle.

$\bold{\underline {5)Circumference \: of \: a \: circle:-}}$The perimeter of a circle is called its circumference. In other words, the length of the boundary of the interior of a circle is its circumference.

Answer 2

Circle

In geometry, a circle is a closed curve formed by a set of points on a plane that are the same distance from its center O. That distance is known as the radius of the circle.

Diameter

The diameter of a circle is a line segment that passes through the center of the circle and has its endpoints on the circle. All the diameters of the same circle have the same length.

Chord : A line segment within a circle that touches two points on the circle is called chord of a circle.

Secant of circle : A line that intersects a circle at two points then it is called Secant of circle.

In geometry, the circumference (from Latin circumferens, meaning "carrying around") of a circle is the (linear) distance around it. That is, the circumference would be the length of the circle if it were opened up and straightened out to a line segment. Since a circle is the edge (boundary) of a disk, circumference is a special case of perimeter. The perimeter is the length around any closed figure and is the term used for most figures excepting the circle and some circular-like figures such as ellipses. Informally, "circumference" may also refer to the edge itself rather than to the length of the edge.
