Introduction to Circles

A circle is a fundamental shape in geometry, defined as all points equidistant from a center point. Understanding circle parts and properties is essential for many mathematical applications.

Circles appear everywhere in nature and design - from wheels and gears to planets and orbits. Learning circle vocabulary and relationships prepares you for advanced geometry.

In this lesson, you'll learn the parts of a circle, including radius, diameter, chord, and arc, and understand their relationships.
