The longest chord of a circle is its diameter
. . the chord.
yes.. the largest chord in the circle is the diameter itself..
The cord of a circle that contains the center of that circle is a diameter of that circle.
Every chord is a line on the inside between two points on the circle. A diameter does that, so it's a chord. But in order to be a diameter, a chord also has to meet another requirement ... it has to go through the center of the circle. A lot of chords don't do that, so they can't be diameters.
