A circle is a two-dimensional shape consisting of all points in a plane that are equidistant from a fixed point called the center. It is characterized by its radius, diameter, circumference, and area, and plays a fundamental role in geometry and trigonometry.

two-dimensional shape

A fixed point is a value that remains constant under a given function or transformation, meaning that when the function is applied to this value, it returns the value itself. Fixed points are crucial in various fields such as mathematics, computer science, and physics, where they help in understanding stability, convergence, and equilibrium states.

the center

The radius of a circle or sphere is the distance from its center to any point on its boundary, serving as a fundamental measure in geometry. It is crucial in calculating other properties such as the diameter, circumference, and area, and is used in various mathematical and physical applications.

radius

The diameter of a circle is the longest distance across it, passing through the center, and is twice the length of the radius. It is a critical measure in geometry, influencing calculations of circumference and area, and is a fundamental property of circles and spheres.

diameter

The circumference of a circle is the distance around its edge, often calculated using the formula C = 2πr, where r is the radius. It is a fundamental concept in geometry that connects linear and angular measurements, highlighting the relationship between a circle's diameter and its perimeter through the constant π (pi).

circumference

Area is a measure of the extent of a two-dimensional surface or shape in a plane, quantified in square units. It is a fundamental concept in geometry and mathematics, essential for calculating the size of surfaces in various fields such as architecture, engineering, and physics.

area

Geometry is a branch of mathematics concerned with the properties and relationships of points, lines, surfaces, and shapes in space. It encompasses various subfields that explore dimensions, transformations, and theorems to understand and solve spatial problems.

geometry

Trigonometry is a branch of mathematics that studies the relationships between the angles and sides of triangles, particularly right-angled triangles. It is essential in various fields such as physics, engineering, and computer science for solving problems involving periodic phenomena and spatial relationships.
