Central angle intersection points and of the legs of the angle with the circle form a diameter, then is a straight angle. (In radians, .) Let be the minor arc of the circle between points and , and let be the radius of the circle. If the central angle is subtended by , then If the central angle is not subtended by the minor arc , then is a reflex angle and If a tangent at and a tangent at intersect at the exterior point , then denoting the center as , the angles (convex) and are supplementary (sum to 180°).

Center for Women in Mathematics Center for Women in Mathematics The Center for Women in Mathematics, a part of the Smith College Department of Mathematics and Statistics, is an American educational program founded in 2007 to increase the involvement of women in mathematics. The Center aims for students to engage in coursework and research in a mathematical environment that actively supports women. The Junior Program is designed for undergraduate women who wish to spend a year or a semester studying mathematics at a women's college. Financial aid funding is provided by the National Science Foundation. The Post-Baccalaureate Program is geared towards women with bachelor's degrees
