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

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 ...

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, ...

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 ...

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 ...

Following the rules. Most geometry used in everyday life is the geometry of flat spaces, or Euclidean geometry, so called because the Greek mathematician Euclid wrote down many of its principles ...

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.” ...
