How do you find the measure of an inscribed angle?
You find the arc measure and then you divide it in half to find the inscribed angle
What is the relation between inscribed angle and central angle of minor arc?
minor arc of cord is half of major arc of same cord
Is an inscribed angle congruent to the arc?
No, it can never be. One is an angle and the other is a curved line!
The central angle of a minor arc is than inscribed angle of its corresponding major arc?
This cannot be answered. This does not make any sense.
Explain the difference between a central angle and an inscribed angle?
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.
How do you work out angles in a semi-circle?
An inscribed angle is an angle formed by two chords in a circle which have a common endpoint. This common endpoint forms the vertex of the inscribed angle.The other two endpoints define an intercepted arc on the circle Any angle inscribed in a semi-circle is a right angle. The proof is simply that the intercepted arc is 180 so the angle must be half of that or 90 degrees.
What is the relation between the arc length and angle for a sector of a circle?
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.
What is an inscribed angle on a circle?
An arc.
How do you find the measure of an inscribed angle?
You find the arc measure and then you divide it in half to find the inscribed angle
Is an inscribed angle which intercepts a major arc an obtuse angle?
Well, not always. An obtuse angle is one that is greater than 90 degrees. Any inscribed angle that intercepts a major arc can be any measurement in which it intercepts.
What is the relation between inscribed angle and central angle of minor arc?
minor arc of cord is half of major arc of same cord
Is an inscribed angle congruent to the arc?
No, it can never be. One is an angle and the other is a curved line!
The central angle of a minor arc is than inscribed angle of its corresponding major arc?
This cannot be answered. This does not make any sense.
What is a region formed by two radii's and the arc between the endpoints called?
Segment

What is the measure of an arc that is intercepted by an inscribed angle of 30 degrees?
60 degrees
Which of the following is part of the area of a circle formed by an arc and two radii which intersect the endpoints of the arc?
it the circumference of a circle
