Hello!

Parts of a Circle

• A Radius is the line segment that stretches from the center of the circle to the outer curve.
• A Diameter is the line segment that stretches from side to side of a circle that goes through the center of the circle.
• The Circumference is the length of the outer border of the circle.

Given the definitions, we are simply looking for any line that goes through the center of the circle, and touches twice on the circumference of the circle.

There are only two lines that seem to go through the circle, and have endpoints on the circle:

• CF
• AD
