“Down with Euclid! Death to triangles!” Luckily, triangles survived nonetheless—and thrived. In “Love Triangle: How ...

Greek geometry wasn’t just math—it was an attempt to decode the universe. Its logic still powers rockets, bridges, and every GPS route today.

This book provides an inquiry-based introduction to advanced Euclidean geometry. It utilizes dynamic geometry software, specifically GeoGebra, to explore the statements and proofs of many of the most ...

So we're going to take a look at non-Euclidean geometry, or the geometry that deals with 3D surfaces such as spheres or saddle shapes. That's where things like triangles start to get weird. Take a ...

This object, considered an “impossible figure”, is formed by three bars that appear to connect at right angles, forming a triangle. However, this structure defies several laws of Euclidean geometry, ...

Also, in hyperbolic geometry, the sum of the angles of the triangles is less than 180 degrees. For example, the sum of the angles of the triangles on the Poincare disk below is 30 degrees + 90 ...

VideoThere's a simple way to learn geometry over the summer. It is easy and fun. Imagine Euclidean geometry: the video game. If your experience in high school geometry was anything like mine, it ...

In “Love Triangle: How Trigonometry Shapes the World,” Matt Parker recounts, for instance, how computers were a “game-changer in the field of shape finding.” ...
