Explanation: Because the circle is the set of all points in a plane that are equidistant, and the given point that is called 'Center'.
2. Radius
Explanation: Because the half of the diameter or the distance from the midpoint to the circle border, it is called the radius of a the circle.
3. Circumference
Explanation: Because the meaning of circumference is carrying around and it would be the arc leng and of a circle and it straightened the line segment.
4. Semi Circle
Explanation: is a one-dimensional locus of points that forms half of a circle.
5. Central angle
Explanation: is a region bounded by two radii of a circle and the intercepted arc of the circle
6. Diameter
Explanation:Since a diameter consists of two radii joined at their endpoints, every diameter has length equal to twice the radius.
7. Chord
Explanation: 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.
8. Arc
Explanation: Types of arcs. A chord, a central angle or an inscribed angle may divide a circle into two arcs. The smaller of the two arcs is called the minor arc.
9. Radii
Explanation: or the conventional English plural radiuses.
10. Center
Explanation: The parts of a circle include a radius, diameter and a chord. All diameters are chords, but not all chords are diameters.
