Question

The types of Geometry that mathematicians study are:
A. Euclidean
B. non-Euclidean
C. Both Euclidean and non-Euclidean
D.There are many types

Answer 1

C. Both Euclidean and non-Euclidean

Answer 2

Non-Euclidean Geometries: are any forms of geometry that contain a postulate (axiom) which is equivalent to the negation of the Euclidean parallel postulate.

Euclidean Geometry: (the high school geometry we all know and love) is the study of geometry based on definitions, undefined terms (point, line and plane) and the assumptions of the mathematician Euclid.

Answer 3

I personally think it's D
As there is Euclidean and Non-Euclidean

But you also study Algebraic and Differential Geometry...
