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.
Application of relation between arc of length and central angle?
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.
How are inscribed angles different from central angles?
Inscribed angles and central angles differ in their definitions and the way they relate to a circle. A central angle is formed by two radii extending from the center of the circle to the circumference, while an inscribed angle is formed by two chords that meet at a point on the circle itself. The measure of a central angle is equal to the arc it subtends, whereas an inscribed angle measures half of the arc it intercepts. This fundamental difference affects their geometric properties and applications in circle-related problems.
How do inscribed angles help you understand angles that occur outside the circle?
why dont the central angle change regardless the size of the circle
What is the relation between the arc length and pi?
arc length/2pi*r=measure of central angle/360
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.

How does the central angle compare to the inscribed angle if it is on the same side of a common chord?

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 inscribed angle?
An inscribed angle is an angle with its vertex on a circle and with sides that contain chords of the circle.
