We can measure the angle the spot subtends in the night sky — one of the three angles of the triangle. Then we can check whether the combination of side lengths and angle measure is a good fit for ...

In spherical geometry, ... and the total angle of triangles in spherical or hyperbolic geometry is said to be very small compared to the total angle of triangles in a plane universe.

That’s Maths: Spherical geometry is central to the study of geophysics and astronomy ... The three angles of a plane Euclidean triangle add to two right angles or 180 degrees.

In Euclidean geometry, the problems and shapes deal with flat surfaces. But the world isn't flat. ... In other words, the larger the triangle is on a spherical shape, ...

“Geometry has completely changed how I view the world around me and has led me to reexamine all the geometric facts and theorems I had just assumed to be true in high school,” said Sarah Clarke ’23.
