Chords

A chord is a straight line connecting two points on the circle.

Chords in Geometry

The diameter is a special chord, which passed through the center of the circle, and its length is 2*r. It is the longest possible chord in the circle.

Now that we've explained the basic concept of chords in geometry, let's scroll down to work on specific geometry problems relating to this topic.
