Circle Geometry Concepts

This video tutorial explains various terms and labels associated with circles. It covers the definitions and characteristics of a radius, diameter, circumference, chord, tangent, sector, segment, and arc length. Each term is described in relation to its position and function within a circle, providing a comprehensive understanding of circle geometry.

What is the term for a line that extends from the center to the edge of a circle?

• Diameter

• Chord

• Tangent

• Radius

How is a diameter related to a radius?

• It is unrelated to the radius

• It is equal to the radius

• It is double the radius

• It is half the radius

What do we call the perimeter of a circle?

• Diameter

• Circumference

• Radius

• Chord

Which line goes from one edge of the circle to the other without passing through the center?

• Diameter

• Chord

• Radius

• Tangent

What is a line called that just touches the edge of a circle?

• Tangent

• Diameter

• Radius

• Chord

What shape does a sector of a circle resemble?

• A triangle

• A rectangle

• A straight line

• A slice of pizza

What is a segment in a circle?

• A line that touches the circle

• A line from the center to the edge

• A part of the circle cut off by a chord

• The perimeter of the circle

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

• Arc length

• Diameter

• Chord

• Tangent

Which of the following is not a part of a circle?

• Radius

• Diameter

• Square

• Circumference

What is the main difference between a chord and a diameter?

• A chord passes through the center

• A diameter passes through the center

• A diameter is shorter than a chord

• A chord is the perimeter of the circle
