In the realm of non-Euclidean geometry, where the familiar rules of Euclid’s postulates are challenged and alternative geometric systems unfold, the Pythagorean theorem takes on a fascinating transformation. Here, the theorem undergoes modifications and adaptations to accommodate the unique properties and curvatures of non-Euclidean spaces.

In hyperbolic geometry, one of the prominent branches of non-Euclidean geometry, the Pythagorean theorem experiences a delightful alteration. Rather than the classic formulation of a^2 + b^2 = c^2, where ‘a’ and ‘b’ represent the lengths of the legs of a right triangle and ‘c’ denotes the length of the hypotenuse, a modified version emerges.

In this modified Pythagorean theorem within hyperbolic geometry, the equation takes the form a^2 + b^2 < c^2. Yes, you read that correctly! The sum of the squares of the lengths of the legs is now less than the square of the length of the hypotenuse. This intriguing departure from Euclidean geometry stems from the inherent curvature and non-Euclidean nature of hyperbolic space.

Similarly, in elliptic geometry, another captivating branch of non-Euclidean geometry, the Pythagorean theorem experiences yet another transformation. Here, the modified theorem takes the form a^2 + b^2 > c^2, where the sum of the squares of the lengths of the legs surpasses the square of the length of the hypotenuse. The curvature of elliptic space gives rise to this intriguing alteration, challenging the familiar Euclidean notions.

These modified versions of the Pythagorean theorem within non-Euclidean geometries reflect the profound impact of spatial curvature on geometric relationships. They demonstrate the versatility and adaptability of mathematical principles as they transcend the boundaries of Euclidean geometry.
