What is the role of the center in a circle?

• To divide the circle into two equal arcs

• To define the circle's boundary

What does the circumference of a circle represent?

• The line intersecting the circle at two points

What distinguishes a diameter from a chord?

• A diameter connects any two points on the circle

• A diameter is any line segment from the center to the circumference

• A diameter is the longest possible chord in a circle and goes through its center

• A diameter is a line touching the circle at one point

Define a chord in the context of a circle.

• A line segment with both ends on the circumference but not passing through the center

• The distance around the circle

• The shortest distance across the circle through its center

• A line intersecting the circle at two points
