A diameter is a a chord that contains the center of the circle.

Example Solution: SU

Practice makes perfect

Before naming a chord from the graph, let's review some important definitions about circles.

Chord: A segment whose endpoints are on the circumference of a circle.
Diameter: A chord that contains the center of the circle.

Now, consider the given diagram. We can see that the endpoints of SU are on the circumference of the circle and that it also passes through the center R.

Therefore, according to the definitions, SU is a chord and a diameter of the circle. Note that this is only one of the many names this line can take.
