Accreditation is a process in which school standards are evaluated by an accreditation agency. In the United States, this process is not completed by the federal government, but by states or private companies with varying rules and standards. Different groups promote accreditation for homeschoolers.
The circle is the simplest and best known conic section. As a conic section, the circle is the intersection of a plane perpendicular to the cone's axis. The geometric definition of a circle is the locus of all points a constant distance r {\displaystyle r} from a point ( h , k ) {\displaystyle (h,k)} and forming the circumference (C).
In geometry, a circular segment is a region of a circle which is cut off from the rest of the circle by a secant or a chord. More formally, a circular segment is a region of two-dimensional space that is bounded by an arc of a circle and by the chord connecting the endpoints of the arc.
