Euclidean geometry crying in the corner while non-Euclidean geometry flexes with its mind-bending rules! In standard Euclidean geometry, an equilateral triangle (all sides equal) can't also be a right triangle (one 90° angle) because angles in a triangle must sum to 180°. But switch to a spherical surface and suddenly geometry goes wild! On a sphere, you can create a triangle with three 90° angles—adding up to 270°—completely breaking Euclidean rules. That spherical diagram is literally showing how triangles on curved surfaces can have properties that would make your high school geometry teacher have an existential crisis.
Non-Euclidean Go Brrrrrr
