WebAn inscribed angle is an angle with its vertex "on" the circle, formed by two intersecting chords. The measure of the inscribed angle is half that of the arc that the two sides cut out of the circle, specifically, `A hat(0) B = (hat(AB))/2`. Exterior Angle: An exterior angle has its vertex where two rays share an endpoint outside a circle.
WebJul 9, 2024 · A circle has a total of 360 degrees all the way around the center, so if that central angle determining a sector has an angle measure of 60 degrees, then the sector … Webis the central angle that intercepts , so . Therefore, we need to find to obtain our answer. If the sides of an angle with vertex outside the circle are both tangent to the circle, the angle formed is half the difference of the measures of the arcs. Therefore, Letting , since the total arc measure of a circle is 360 degrees,
