It is an angle formed by two rays whose vertex is the center of the circle.
central angle
5
It is an arc of the circle that measures less than a semicircle. It is named usually by using the two endpoints of the arc.
minor arc
5
It is an angle whose vertex is on a circle and whose sides contain chords of the circle.
inscribed angle
5
It is the arc that lies in the interior of an inscribed angle and has endpoints on the angle.
intercepted arc of the angle
5
It is an arc of a circle that measures greater than a semicircle. It is name by using the two endpoints and another point on the arc.
major arc
5
The degree measure of a minor arc is the measure of the central angle which intercepts the arc. True or False.
True
5
It is an arc with a measure equal to one-half the circumference of a circle. It is named by using the two endpoints and another point on the arc.
semicircle
5
The degree measure of a major arc is equal to 360 minus the measure of the minor arc with the same endpoints. True or False.
True
5
If an angle is inscribed in a circle, then the measure of the angle equals one-half the measure of its intercepted arc or the measure of the intercepted arc is twice the measure of the inscribed angle. True or False.
True
5
If an inscribed angle of a circle intercepts a semicircle, then the angle is an acute angle. True or False.
