a circle has no vertex.
\n" ); document.write( "if you mean an angle whose vertex lies on the circumference of a circle, then you are talking about an inscribed angle.
\n" ); document.write( "a central angle has its vertex at the center of the circle.
\n" ); document.write( "the degree measure of a central angle is equal to the degree measure of its intercepted arc.
\n" ); document.write( "the degree measure of an inscribed angle is equal to 1/2 the degree measure of its intercepted arc.
\n" ); document.write( "the intercepted arc is the part of the circumference of the circle that is between the sides of the angle formed.
