Front

What is a major arc?

Back

A major arc is a part of a circle that measures greater than 180 degrees.

Front

What is a minor arc?

Back

A minor arc is a part of a circle that measures less than 180 degrees.

Front

What is a diameter?

Back

A diameter is a line segment that passes through the center of a circle and has its endpoints on the circle.

Front

What is the relationship between a diameter and a radius?

Back

The diameter is twice the length of the radius.

Front

What is the circumference of a circle?

Back

The circumference is the distance around the circle, calculated as C = 2πr, where r is the radius.

Front

What is the area of a circle?

Back

The area of a circle is calculated as A = πr², where r is the radius.

Front

What is a chord in a circle?

Back

A chord is a line segment whose endpoints lie on the circle.

Front

What is the center of a circle?

Back

The center of a circle is the point that is equidistant from all points on the circle.

Front

What is the difference between a sector and a segment of a circle?

Back

A sector is a region bounded by two radii and an arc, while a segment is a region bounded by a chord and an arc.

Front

How do you find the measure of an arc?

Back

The measure of an arc can be found using the central angle that subtends the arc.
