Answer:
A characteristic of spherical geometry is that the sum of the angles of a triangle on the surface of a sphere is greater than 180 degrees.
Explanation:
The fact that a triangle's sum of angles on the surface of a sphere is more than 180 degrees is a feature of spherical geometry. In actuality, the area of a spherical triangle on the sphere's surface is inversely proportional to the sum of its angles. Spherical geometry has this special trait because of the curved structure of the sphere, in contrast to Euclidean geometry, where the sum of the angles of a triangle is always 180 degrees.
