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 your triangle — just like the one above — can seem more like a Euclidean geometry triangle because when you get really close to a curved surface, it looks flat.

In the vast world of geometry and art, there are figures that challenge our perception and understanding of space. One of these figures is the Penrose Triangle, also known as the Tribar. This object, ...

One hypothesis about the shape of the universe is that the universe is in the space of Euclidean geometry and flat. In Euclidean geometry, it is assumed that straight lines extend everywhere ...

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 ...

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

The movement, which thrived for decades, in part viewed Euclidean geometry as insufficient, elevating algebra instead.
