What is a segment from the center of a circle to a point on the circle?
The a line segment from the center of the circle to any point on the circle is a radius of the circle. By definition of a circle, all radii have the same length. We also use the term radius to mean the length of a radius of the circle.
What is a line segment that has 1 endpoint at the center and the other on the circumference?
Radius. A line segment that has 1 endpoint at the center and the other on the circumference. Chord.
What is a segment that contains the center as one of the endpoints?
Chapter 9
| A | B |
|---|---|
| chord | a segment that has its endpoints on the circle |
| diameter | a chord that contains the center of the circle |
| radius | a segment with one endpoint at the center and the other on the circle |
| tangent | a line in the plane of the circle that intersects the circle in exactly one point |
What do you call the longest chord?
A chord that passes through the center of a circle is called a diameter and is the longest chord of that specific circle.
Is the radius is the segment joining the center of the circle?
Radius is a line segment joining the center of the circle and at any point on the boundary of circle..
What is the segment that has both endpoints on the circle?
A diameter is a line segment that has both of its endpoints on the circle and passes through the center. A chord is a line segment with both endpoints on the circle.
Is a segment with endpoints on a circle?
A chord of a circle is a line segment whose endpoints are on the circle.
Is a chord a radius?
Radius: A circle’s radius — the distance from its center to a point on the circle — tells you the circle’s size. In addition to being a measure of distance, a radius is also a segment that goes from a circle’s center to a point on the circle. Chord: A segment that connects two points on a circle is called a chord.
What do you call the perimeter of a circle?
The perimeter of a circle, often called the circumference, is proportional to its diameter and its radius.
