In Euclidean geometry, the sum of the measures of the interior angles of a pentagon is 540°. Predict how the sum of the measures of the interior angles of a pentagon would be different in spherical geometry. A. The sum would be greater than 540°. B. The sum would still be 540°. C. The sum would be less than 540°. D. The sum would less than or greater than, but never equal to, 540°.

OpenStudy (perl):
in elliptic geometry, the angle sum of a triangle is greater than 180 degrees
OpenStudy (perl):
since a pentagon can be dissected into 3 triangles, and each triangle is more than 180 degrees, that implies a pentagon is greater than 3*180 degrees
