Theorems about triangles | Articles containing proofs | Area | Euclidean plane geometry
Pappus's area theorem describes the relationship between the areas of three parallelograms attached to three sides of an arbitrary triangle. The theorem, which can also be thought of as a generalization of the Pythagorean theorem, is named after the Greek mathematician Pappus of Alexandria (4th century AD), who discovered it. (Wikipedia).
Theorem of Pappus (KristaKingMath)
► My Applications of Integrals course: https://www.kristakingmath.com/applications-of-integrals-course Learn how to use the Theorem of Pappus to find the volume of a solid, in this particular case, a right circular cone. Theorem of Pappus tells us that volume is equal to area of the plane

Pappus' theorem and the cross ratio | Universal Hyperbolic Geometry 3 | NJ Wildberger
Pappus' theorem is the first and foremost result in projective geometry. Another of his significant contributions was the notion of cross ratio of four points on a line, or of four lines through a point. We discuss various important results: such as the Cross ratio theorem, asserting the

A Pythagorean Theorem for Pentagons + Einstein's Proof
Pythagoras's Theorem is the most famous theorem in mathematics, commonly stated as "the square on the hypotenuse of a right-angled triangle is equal to the sum of the squares on the other two sides." However, Pythagoras's Theorem is not just for squares. In fact it works for any shape.
