Circles In Geometry, Basic Introduction - Circumference, Area, Arc Length, Inscribed Angles & Chords

Video Description

This geometry video tutorial provides a basic introduction into circles. It explains how to calculate the area of a circle as well as the circumference of a circle. It also explains how to calculate the arc length of a sector as well as the area of a sector in a circle. it explains the difference between the radius, chord, and diameter of a circle. It mentions how to calculate the inscribed angle as well as the measure of the intercepted arc. It discusses how to calculate the area of the shaded region given a right triangle inscribed in a circle.
