​

Answer 1

Answer:

Circumference:

the enclosing boundary of a curved geometric figure, especially a circle.

Area:

the extent or measurement of a surface or piece of land.

Sector:

the plane figure enclosed by two radii of a circle or ellipse and the arc between them.

Secant:

a straight line that cuts a curve in two or more parts.

Chord:

a straight line joining the ends of an arc.

Concyclic points:

a set of points are said to be concyclic if they lie on a common circle.

Concentric points:

two or more points are said to be concentric when they share the same center or axis.

Circumference:

In geometry, the circumference is the perimeter of a circle or ellipse.

Area:

Area of a circle is the region occupied by the circle in a two-dimensional plane.

————————————————————

Sector:

A circular sector or circle sector, is the portion of a disk enclosed by two radii and an arc, where the smaller area is known as the minor sector and the larger being the major sector.

————————————————————

Secant:

a secant of a curve is a line that intersects the curve at a minimum of two distinct points.

————————————————————

Chord:

A chord of a circle is a straight line segment whose endpoints both lie on the circle.

————————————————————

Concyclic point:

a set of points are said to be concyclic if they lie on a common circle.

————————————————————

Concentric circles:

Concentric circles are circles with a common center.
