# Name That Circle Part Quiz Answer Key

## Introduction

Are you ready to test your knowledge of circle parts? Take the Name That Circle Part Quiz and see how many you can identify. This quiz will challenge your understanding of basic geometry concepts and help you improve your math skills.

## Question 1

What is the name of the line segment that connects two points on the circle and passes through the center?

The answer is the diameter. The diameter is the longest chord in a circle and passes through the center. It is also twice the length of the radius.

## Question 2

What is the name of the line segment that connects two points on the circle, but does not pass through the center?

The answer is the chord. A chord is any line segment that connects two points on the circle. It can be any length and does not necessarily pass through the center.

## Question 3

What is the name of the line segment that connects the center of the circle to any point on the circle?

The answer is the radius. The radius is the distance from the center of the circle to any point on the circle. It is half the length of the diameter.

## Question 4

What is the name of the point where the circle intersects with a line or another circle?

The answer is the intersection point. An intersection point is where two or more geometric figures meet. In the case of a circle, it is where the circle intersects with another circle or a line.

## Question 5

What is the name of the line that divides the circle into two equal parts?

The answer is the diameter. The diameter is the only line that divides the circle into two equal parts. Any other line that intersects the circle will create two unequal parts.

## Question 6

What is the name of the curved part of the circle between two points?

The answer is the arc. An arc is a curved part of the circle between two points. It can be any length and measure in degrees.

## Question 7

What is the name of the angle formed by two radii of the circle?

The answer is the central angle. A central angle is an angle formed by two radii of the circle. It measures the angle at the center of the circle.

## Question 8

What is the name of the angle formed by a chord and a tangent line to the circle at the point of intersection?

The answer is the inscribed angle. An inscribed angle is an angle formed by a chord and a tangent line to the circle at the point of intersection. It measures half the angle of the intercepted arc.

## Question 9

What is the name of the angle formed by two tangents that intersect outside the circle?

The answer is the exterior angle. An exterior angle is an angle formed by two tangents that intersect outside the circle. It measures the angle between the two lines.

## Question 10

What is the name of the area enclosed by the circle?

The answer is the circle area. The circle area is the amount of space enclosed by the circle. It can be calculated using the formula A = πr², where r is the radius of the circle.

## Conclusion

Congratulations on completing the Name That Circle Part Quiz! You now have a better understanding of the basic geometry concepts related to circles. Keep practicing and improving your math skills.
