Power Theorems - Chords, Secants & Tangents - Circle Theorems - Geometry

This geometry video tutorial provides a basic introduction into the power theorems of circles which is based on chords, secants, and tangents. It covers the chord chord power theorem, the secant tangent power theorem, and the secant secant power theorem. The chord chord power theorem states that the product of the segments of two intersecting chords are equal. The secant tangent power theorem states that the square of the tangent segment is equal to the product of the secant and the external part of the secant segment when the tangent of the circle and the secant of the circle extend from a common endpoint outside of the circle. The secant secant power theorem states the products of the secants and the external part of the secant segments are equal. This geometry video contains plenty of examples and practice problems on circle theorems.
