It is a straight angle.

∙ 7y agoIt is the subtended angle of the arc
The angle can have any value in the range [0, 360) degrees.
That's a "central angle", but the part that really fascinates me is this: What would it look like if you hadan angle whose vertex was in the center of the circle and whose sides didn't intersect ? ? ?
An angle perhaps
It is called the vertex of the angle.

It can be any angle above zero and below 180 degrees. When it becomes 180 degrees then the two side will be a straight line. It is also defined as the included angle of a circular sector.

No, because if a circle has a set amount of sides, then it must have a certain amount of angles, reguiring the vertex of the angle to be farther from the center than say,the midpoint of its adjacent angle. This violates a criterion of a circle, because not all (no matter how small the difference is) radii are equidistant from the center.
each side of a angle is a vertex * * * * * No, the point where the sides meet is the vertex. The sides themselves are ... just sides.
you can name a vertex with b
