Circle Geometry Vocabulary

Central Angle: Intersects a circle at two points, vertex located at the circle's center.
Chord: A segment whose endpoints lie on the circumference of a circle.
Circle: A set of points equidistant from a central point, known as the center.
Circumference: The total distance around the circle.
Circumscribed Circle: A circle that encompasses all vertices of a polygon, forming a boundary.
Diameter: The longest chord, passing through the center of a circle, measuring twice the radius.
Inscribed Polygon: A polygon with all vertices located on a circle.
Intercepted Arc: An arc is intercepted when endpoints lie on an angle with all other points within the circle's interior.
Major Arc: An arc measuring greater than 180 degrees.
Minor Arc: An arc measuring less than 180 degrees.
Pi (π): An irrational number, given by the ratio of a circle's circumference to its diameter, approximately equal to 3.14159.
Point of Tangency: The single point where a tangent line intersects the circle.
Radius: A segment connecting the center of the circle to any point on its circumference.
Secant Line: A line that intersects the circle at two distinct points.
Semicircle: An arc that spans half a circle, measuring exactly 180 degrees.
Tangent Line: A line that touches the circle at one point, not penetrating the circle.
