Circles - Chords, Radius & Diameter - Basic Introduction - Geometry

This geometry video tutorial provides a basic introduction into circles as relates to chords, the radius of a circle as well as its diameter. If a radius bisects a chord, it is always perpendicular to that chord. Also, if two chords are equidistant from the center of a circle, the two chords are congruent. This video contains a few practice problems on congruent chords. This tutorial explains how to calculate the radius of a circle given the distance of a chord from the center of a circle as well as the length of the chord. It also explains how to calculate the radius of a circle if a rectangle is inscribed inside of it.
