I found an easy-to-understand definition of accredited homeschooling on Wikipedia: Accreditation is a type of quality assurance process under which a facility's or institution's services and operations are examined by a third-party accrediting agency to determine if applicable standards are met.

In primitive geometrical terms, an ellipse is the figure you can draw in the sand by the following process: Push two sticks into the sand. Take a piece of string and form a loop that is big enough to go around the two sticks and still have some slack.
A circle is a set of all points in a plane that are all an equal distance from a single point, the center. The distance from a circle's center to a point on the circle is called the radius of the circle. A radius is a line segment with one endpoint at the center of the circle and the other endpoint on the circle. For the circle below AD, DB, and DC are radii of a circle with center D. A line segment that crosses the circle by passing through the center of the circle is called the diameter. The diameter twice the length of the radius. In the circle above AC is the diameter of the circle. A chord is a segment that also has endpoints on the circle, but the line does not need to cross through the center. On the circle below BC and AC are chords. A diameter is a chord that passes through the center of the circle. A secant is a line that intersects with a circle at 2 different points.
