Question: 1 / 400

When considering properties of circles, what does the term 'chord' refer to?

A tangent created from the center

A line within the circle

A line segment joining two points on the circle

The term 'chord' in the context of circles specifically refers to a line segment that joins two points on the circumference of the circle. This definition is critical because a chord is distinct from other elements associated with a circle, such as tangents and diameters.

A chord does not need to pass through the center of the circle; it simply has to connect any two points on the circle's boundary. This means that every diameter is a special type of chord, specifically the longest one, but not all chords are diameters. In essence, a chord can vary in length and position, making it an essential concept when analyzing circle geometry, especially when considering the relationship between chords, arcs, and angles formed within the circle.

Understanding this definition helps in solving various problems related to circle theorems and properties, reinforcing the importance of accurately grasping geometric terms.
