Answer:
A circle is the set of all points in the plane that are the same distance away from a specific point, called the center. The center of the circle below is point A. We call this circle “circle A,” and it is labeled ⨀A.
Important Circle Parts
Radius: The distance from the center of the circle to its outer rim.
Chord: A line segment whose endpoints are on a circle.
Diameter: A chord that passes through the center of the circle. The length of a diameter is two times the length of a radius.
Secant: A line that intersects a circle in two points.
Tangent: A line that intersects a circle in exactly one point.
Point of Tangency: The point where a tangent line touches the circle.
