Spherical pythagorean theorem
WebAug 12, 2024 · The Pythagorean theorem is justifiably the most popular and at the same time the most majestic theorem of mathematical science. Other than his famous theorem, Pythagoras was credited with many mathematical and scientific discoveries, including Pythagorean tuning, the five regular solids, the Theory of Proportions. The Pythagorean theorem generalizes beyond the areas of squares on the three sides to any similar figures. This was known by Hippocrates of Chios in the 5th century BC, and was included by Euclid in his Elements: If one erects similar figures (see Euclidean geometry) with corresponding sides on the sides of a right triangle, then the sum of the areas of the ones on the tw…
