Math Geometry, Circle and Angle

A circle is the set of all points in a plane at a fixed distance (radius. Circles are simple closed curves, dividing the plane into an interior and exterior. Sometimes the word circle is used to mean the interior, with the circle itself called the circumference. Circumference means the length of the circle and the interior of the circle is called a disk.The circumference of a circle can be calculated from its diameter using the formula: C = pi * diameter or C = 3.14159 * 2 * radius

An angle is a combination of two rays with a common endpoint which is called as vertex. There are several angle units but major ones are degree and radian. Degree is 1/360 of a full circle and radian is the angle subtended by an arc of a circle that has the same length as the circle's radius.
