Circle Geometry

Circle geometry studies the properties and relationships of points, lines, and angles associated with circles. Key concepts include the circle's center, radius (distance from center to any point on the circle), diameter (longest distance across the circle), and circumference (the perimeter). It explores how angles relate when formed by chords (lines connecting two points on the circle), tangents (lines touching the circle at one point), and secants (lines crossing the circle). Theorems like the inscribed angle theorem describe how angles are measured within the circle. Overall, circle geometry helps us understand the structure and relationships of circular shapes in various contexts.
