Parts of a Circle

What defines the center of a circle?

• The point equidistant from all edges of the circle

• The longest chord of the circle

• A line that touches the circle at one point

• A part of the circumference

What term describes the boundary measurement of a circle?

• Arc

• Diameter

• Radius

• Circumference

How is the radius of a circle defined?

• Line joining two points on the circle

• Straight line passing through the center

• Distance from center to any point on circumference

• Longest possible chord of the circle

What is a sector of a circle?

• A line touching the circle at a single point

• A straight line intersecting the circle at two points

• Region enclosed by two radii and an arc

• The longest chord of the circle

What is the role of a diameter in a circle?

• It's a line that touches the circle at one point only

• It's the same as the radius

Which statement best describes a chord of a circle?

• A line that intersects the circle at one point

• A line inside the circle touching two points on the circumference

• The distance from the center to the circumference
