Question

Which statements about the sum of the interior angle measures of a triangle in Euclidean and non-Euclidean geometries are true? A) In Euclidean geometry, the sum of the interior angle measures of a triangle is 180 degrees, but in elliptical or spherical geometry, the sum is less than 180 degrees. B) In Euclidean geometry, the sum of the interior angle measures of a triangle is 180 degrees, but in elliptical or spherical geometry, the sum is greater than 180 degrees. C) In Euclidean geometry, the sum of the interior angle measures of a triangle is less than 180 degrees, but in hyperbolic geometry, the sum is equal to 180 degrees. D) In Euclidean geometry, the sum of the interior angle measures of a triangle is greater than 180 degrees, but in hyperbolic geometry, the sum is less than 180 degrees. In Euclidean geometry, the sum of the interior angle measures of a triangle is 180 degrees, but in hyperbolic geometry, the sum is less than 180 degrees.
