WebA semicircle is the union of the endpoints of a diameter and all the points of the circle lying on one side of the diameter. An inscribed angle is an angle whose vertex lies on the circle and whose sides contain chords of a circle. 2 hº Angle 2 is an inscribed angle. Before we start, let’s look at two theorems. Theorem WebA circle is a locus of points that are at a fixed distance from a fixed point on a two-dimensional plane. The fixed point is called the center of the circle and the fixed distance is called the radius. In this article, we will explore …
