I believe what you're looking for is called a secant, although it can also be a line, not just a segment.
The radius of a circle is a line segment joining any point of the boundary of the circle to its centre. A diameter is a line segment from a point of the boundary of the circle which passes through the centre and ends at the boundary on the opposite side.
It's Called The Radius
A. If the line segment touches two points on the circle it is called as: 1. secant; if the line extends outside the circle. 2. chord; if the line is present only within the circle. B. If the line segment touches one point on the circle AND the center of the circle AND is present only within the circle it is called as: radius.
A segment of a circle is known as an arc.A segment of a circle is called a arc.A segment of a circle is known as an arc.
That's called a 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.
The point from where an azimuth originates is the center of an imaginary circle.
A segment with end points on a circle is a chord.
A segment with end points on a circle is a chord of that circle.
This segment would be the radius of a circle.
A chord is a line segment whose endpoints lie on a circle. A secant is a line (or line segment) that intersects a circle in two places, endpoints NOT on the circle.
what about such a line segment? the length of such a segment is called the radius. the area of the circle is pi*the length of this segment squared the circumference is 2*pi*the length of this segment
