What is a central angle and what is the relationship of the central angle and the intercepted arc?
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.
The sides of a central angle are two of the circle?
radii
An inscribed angle is an angle formed by two radii which share an endpoint?
False
How do you devide a circle into 7 equal parts?
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.
What is the part of the circle enclosed by two radii?
A part of a circle enclosed by two radii is called a sector.
What is the angle called that is formed by two radii with a vertex at the enter of a circle?
It is called the central angle. Hope that helped!
What do you call a quarter of a circle?
A quarter of a circle, formed by two radii forming a right angle at the centre, is called a quadrant.
What is an angle whose vertex is at the center of a circle?
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.

What do you call the angle whose vertex is at the center of the circle and whose sides are the radii of the circle?
It is the subtended angle of the arc

When piece of a circle is determined by two radii that piece is best called a?
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.
