Break Down the Problem

1. Identify the characteristics of the chord described in the question.
2. Analyze the options provided to find the one that accurately defines the chord that passes through the center of a circle.

Relevant Concepts

• A chord is a line segment whose endpoints lie on the circle.
• A chord that passes through the center of the circle is specifically defined in geometry.

Analysis and Detail

1. The definition of a diameter: In geometry, a diameter is defined as a chord that passes through the center of the circle, dividing it into two equal halves.
2. Examine the other options:
   • Radial chord: This term is not standard in geometry.
   • Circumference: This refers to the distance around the circle, not a line segment.
   • Radius: This is a line segment from the center of the circle to any point on the circle, not a chord.

Verify and Summarize

After analyzing each of the options, it is clear that the correct term for a chord that runs through the center of a circle is indeed "diameter."
