minor arc of cord is half of major arc of same cord
A central angle has its vertex at the center of a circle, and two radii form the Arms. Central angle AOC is described as subtended by the chords AC and by the arc AC. An inscribed angle has its vertex on the circle, and two chords form the arms. Inscribed angle ABC is also described as subtended by the chord AC and by the arc AC.
The relation between the arc of length and the central angle is that the arc of length divided by one of the sides is the central angle in radians. If the arc is a full circle, then the central angle is 2pi radians or 360 degrees.
The inscribed angle forms the apex of the angle. It is a point. To circumscribe the point is 360 degrees. So the inscribed angle and the reflex (outscribed) angle sum to a total of 360 degrees.
arc length/2pi*r=measure of central angle/360

A sector is the area enclosed by two radii of a circle and their intercepted arc, and the angle that is formed by these radii, is called a central angle. A central angle is measured by its intercepted arc. It has the same number of degrees as the arc it intercepts. For example, a central angle which is a right angle intercepts a 90 degrees arc; a 30 degrees central angle intercepts a 30 degrees arc, and a central angle which is a straight angle intercepts a semicircle of 180 degrees. Whereas, an inscribed angle is an angle whose vertex is on the circle and whose sides are chords. An inscribed angle is also measured by its intercepted arc. But, it has one half of the number of degrees of the arc it intercepts. For example, an inscribed angle which is a right angle intercepts a 180 degrees arc. So, we can say that an angle inscribed in a semicircle is a right angle; a 30 degrees inscribed angle intercepts a 60 degrees arc. In the same or congruent circles, congruent inscribed angles have congruent intercepted arcs.

the measure of the inscribed angle is______ its corresponding central angle
Inscribed angle
The central angle is double the measure.
The inscribed angle forms the apex of the angle. It is a point. To circumscribe the point is 360 degrees. So the inscribed angle and the reflex (outscribed) angle sum to a total of 360 degrees.

An inscribed angle is an angle with its vertex on a circle and with sides that contain chords of the circle.
Yes all inscribed angles in a circle have their vertex on the circumference of the circle. Central angles have their vertex at the center of the circle.
The center of an inscribed angle is either a vertex or an endpoint.
