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 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.
A part of a circle enclosed by two radii is called a sector.
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

I always called it an arc. It is simply a section of the circle. The ends are determined by the two radii you referenced. Each of the radii start at the center of the circle and end at their intersection with the circle. The portion of the circle that lies between the ends of the two radii is an arc.
