What is the term for a line segment from the center to any point on a circle?

Diameter
Radius
Chord
Secant

The correct answer is: Radius

The term for a line segment that extends from the center of a circle to any point on the circumference is known as a radius. In geometry, the radius helps define the size of a circle. It is half the length of the diameter, which connects two points on the circle and passes through the center. When visualizing a circle, you can think of multiple radii that can be drawn from the center to various points on the edge, each being equal in length to the radius of that circle. This concept is fundamental in understanding various properties and theorems related to circles, such as those involving circumference, area, and the relationship between the radius and diameter.
