“Embrace change, considering non-Euclidean geometry” offers a basic introduction to the geometry of curved surfaces in which the sum of the degrees of a triangle may equal more or less than 180°. The discussion is enhanced by numerous hand-drawn sketches, including triangles on spheres and saddles. Mathematics students and enthusiasts are encouraged to embrace change as a way to alleviate boredom, understand one’s strengths, and uncover new opportunities and modes of thinking. At the chapter’s end, readers may check their understanding by working on a problem. A solution is provided.

Keywords:   non-Euclidean geometry, geometry, sphere, saddle, triangle, math, student
