A chordof a circle is a geometric line segment whose endpoints both lie on the circle. A secantor a secant line is the line extension of a chord. More generally, a chord is a line segment joining two points on any curve, such as but not limited to an ellipse. A chord that passes through the circle's center point is the circle's diameter.
It is the radius
A line segment with the center of a circle as one endpoint and the other endpoint on the circumference of the circle is a rdius of that circle.
If you mean "radius," it's a straight line from the center to the circumference of a circle or sphere.
A chord is a line that joins to points on the circumference of a circle. If it passes through the center of the circle it's called a diameter.
Circumference is the perimeter of a circle Diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints are on the circle
The diameter.
Diameter is the length of a straight line passing through the center of a circle or sphere and connecting two points on the circumference of the circle or the surface of the sphere. Circumference is the length of the closed curve of a circle.
A straight line touching the circumference of circle at one point is a tangent
Diameter.
The word diameter is a noun. It is any straight line between two points on the circumference of a circle ensuring it passes through the center of the circle.
A chord is a straight line that spans the circumference of a circle and the diameter of a circle is a straight line in a circle spanning its circumference and passing through the circle's centre.
It is the tangent of the circle
