A circle is a round-shaped figure that has no corners or edges. In geometry, a circle can be defined as a closed, two-dimensional curved shape.
Properties of a Circle
- Circumference: The perimeter or boundary line of a circle.
- Radius: The distance from the center of the circle to any point on its circumference.
- Diameter: Twice the radius, and the longest distance across the circle.
- Pi (π): The ratio of the circumference to the diameter, approximately 3.14159.
