In a circle, a central angle is formed by two radii. By definition, the measure of the intercepted arc is equal to the central angle.

A part of a circle enclosed by two radii is called a sector.
A circular sector is formed by two radii and an arc. And the angle formed due to the two radii is central angle(Θ). Area of a sector = (Θ/360) πr2.If we divide a circle into seven sectors having equal central angles then the circle is divided into seven equal parts.Angle of the whole circle is 360o. So we should divide the whole angle into 7 equal parts each measuring 360o/7 and then forming the corresponding sectors.
It is called the central angle. Hope that helped!

A quarter of a circle, formed by two radii forming a right angle at the centre, is called a quadrant.
A central angle.The section of the circle formed by that angle and the part of the circle (the part being the circumference) between the radii is called a sector.

It is the subtended angle of the arc
A central angle is formed by two radii in a circle that extend from the center to the circumference, creating an angle at the center. The vertex of the angle is located at the center of the circle, and the two sides of the angle intersect the circle at different points. The measure of the central angle is defined by the arc it subtends on the circle's circumference. Visually, it appears as a wedge shape within the circle.

A pie-shaped portion of a circle, often called a sector, is a section of a circle that is bounded by two radii and the arc connecting their endpoints. It resembles a slice of pie, hence the name. The angle formed at the center of the circle by the two radii defines the size of the sector. This geometric figure is commonly used in various applications, including mathematics and design.
