Study Notes
Key Geometric Terms Related to Circles
- The region between two concentric circles is called an annulus, characterized by its ring shape and defined by the radii of the inner and outer circles.
- A line segment with both endpoints lying on the circumference of the circle is known as a chord; chords can vary in length and are essential in circle geometry.
- The point that is equidistant from all points on the circle is referred to as the center of the circle, a central feature in defining its properties and equations.
- Any connected section of the circle is termed an arc; arcs can represent portions of the circumference and vary in length and size.
- The distance from any point on the circle to the center is known as the radius; it is crucial in determining the circle's size and area.
