Which of the following is not a characteristic of non-Euclidean geometry?. . A.. . Space is saddle-curved.. B.. . The sum of the angles in a triangle is always 180.. C.. . The parallel postulate is false.. D.. . There are no straight lines.

Respuesta :

The correct answer is B) the sum of the angles of a triangle is always 180°.

Explanation:

In Euclidean geometry, we are dealing with two dimensions.  This is why the sum of the measures of the angles of a triangle is 180°.

There are several different non-Euclidean geometries, and depending on the geometry, the angles of a triangle may be more than 180 or less than 180.

Answer:

The correct answer is b) The sum of the angles in a triangle is always 180.
