what is a chord?

A chord is a line dividing a circle. Technically the diameter is a chord, but any line that extends from one edge of a circle and ends on a different part of the edge is a chord.

First, let me give you the definition of a secant of a circle.

Secant of a circle: A line that intercepts a circle in two points.

Now let me give you the definition of a secant segment:

Secant segment: Any segment of a given secant of a circle.

Now let me give you the definition of a chord:

Chord: A secant segment that has both of it's endpoints on the circle.

That's what a chord is in plane geometry (the main field of mathematics that specializes with chords).

There you go, I'm glad I could help. :)
