Definition of a Circle - Radius of a Circle
By yourteachermathhelp
Students learn the definitions of a circle (is a set of points in a plane that are a given distance from a given point in the plane), the given point is called the center, and the distance from the center to the circle is called the radius. Whichever point on the circle is chosen the distance to the center of the circle will be the same, so all radii of a given circle are congruent. Good quality video for grade four and up.
