Every diameter of a circle is chord.
Justify your answer using what you know about diameters and chores. Your teacher will review your answer to ensure you receive proper credit.

True.

A diameter is a line segment that passes through the center of a circle and has both endpoints on the circle.

A chord is a line segment that connects two points on a circle.

Since a diameter passes through the center of a circle, it also passes through any two points on the circle (which would be the endpoints of a chord). Therefore, every diameter of a circle is a chord.
