What is a sector in a circle?

• A line from center to edge

• A line across the circle

• A slice of the circle

• A line touching the circle

What is a segment in a circle?

• A line touching the circle

• A part cut off by a chord

• A line from center to edge

• A slice of the circle

What is the term for the part of the circumference that forms part of a sector?

• Diameter
