Pythagorean Theorem with Curvature Correction

Overview: In curved (non-Euclidean) geometry, the classic Pythagorean relation a 2 + b 2 = c 2 a^2 + b^2 = c^2 for a right triangle must be modified to account for space curvature. One proposed correction is: a 2 + b 2 + h a 2 b 2 R 2 = c 2 , a^2 + b^2 + h\,\frac{a^2 b^2}{R^2} = c^2, where R R is the radius of curvature of the space and h h is a chirality factor that can be +1 or –1 . This formula suggests that the sum of the squares of the legs is not exactly equal to the square of the hypotenuse on a curved surface – there is an extra term proportional to the product a 2 b 2 a^2 b^2 scaled by 1 / R 2 1/R^2 . We will analyze how this curvature term works, the role of the sign h h (positive vs. negative curvature), and how it connects to known geometric laws like the Law of Cosines. We’ll also discuss how different sign choices and values of a , b , c , h a, b, c, h lead to different geometric interpretations, and highlight physical/mathematical contexts where this corrected ...
