Circle Geometry Concepts

This video tutorial covers the basic concepts of circles, including the center, radius, and diameter. It explains the properties of chords and their relationship to the diameter, identifying the diameter as the longest chord. The tutorial also introduces sectors and arcs, describing how they are formed by radii and parts of the circle's boundary. Finally, it discusses circle segments, differentiating between minor and major segments based on their size relative to the chord.
