WebA circle with three points on it. The second point is less than ninety degrees from the first point. The third point is more than one hundred eighty degrees from the second point. An arc made by the first and second point is labeled alpha. The angle made by the first point, the center, and the second point make an angle measuring fifty degrees. WebFinding a Circle's Center. We can use this idea to find a circle's center: draw a right angle from anywhere on the circle's circumference, then draw the diameter where the two legs hit the circle; do that again but for a different diameter; Where the diameters cross is the center!
