Non-Euclidean Geometry: The Forgotten Story

Published on July 18, 2022 by Hemanth

Non-Euclidean Geometry- On the left, a straight line makes right angles to two convex surfaces (hyperbolic). Below this, is a hyperbolic triangle (with angle sum less than 180°) inscribed in a circle. At the centre, a straight line makes right angles with two other straight lines (Euclidean). Below this, a triangle is inscribed in a circle. On the right, a straight line makes right angles with two concave curves (elliptic). Below this, an elliptic triangle is inscribed in a circle.
Non-Euclidean geometry is a well-founded notion in modern science. But this was not always the case. This essay covers the historic race to prove Euclid wrong!
