The measure of the central angle aob is 30

SpletWe know that the angle at the centre of a circle is twice the angle at any point on the remaining part of the circumference. Thus, ∠AOB = (2 × ∠ACB) = (2 × 30°) = 60° Suggest … SpletThe measure of central angle is twice the measure of the inscribed angle subtended by the same arc. (An inscribed angle is an angle whose vertex lies on the circumference of the circle.) The sum of the measures of the central angles of a circle with no common points is 360°. Uses. The central angle theorem is very useful in solving questions ...
