👉 Arc math, also known as hyperbolic geometry, is a non-Euclidean geometry that deals with curves and shapes in spaces where the parallel postulate doesn't hold. Unlike Euclidean geometry, where parallel lines never meet, in hyperbolic geometry, given a line and a point not on that line, there are infinitely many lines through the point that never intersect the original line. This leads to unique properties like the sum of angles in a triangle being less than 180 degrees and the concept of "arcs" that behave differently from their Euclidean counterparts. Arc math uses hyperbolic functions (like sinh, cosh, and tanh) to describe these curved spaces, providing a framework to understand and analyze shapes and relationships in these non-intuitive geometries.
