Mathbits circles (The measure of an entire circle is 360º. MathBitsNotebook Geometry Lessons and Practice is a free site for students (and teachers) studying high school level geometry. A circle is the set of points (locus) equidistant from a given point called the center. In a similar manner, the definition of the area of a circle is also associated with the "areas" of inscribed polygons. It is a slice of a right cone parallel to the circular base of the cone. Pages address central and inscribed angles, angles formed by a tangent and chord, angles formed by two intersecting secants, angles formed by an intersecting tangent and secant, and angles formed by two interesting tangents with this menu driven exploration. This document discusses formulas for angles in circles. center at the origin: B. A = area of circle, r = radius Half of a circle is called a "semicircle".
