that element of geometry which treats associated with the easy properties of straight outlines, groups, jet surface, solids bounded by airplane surfaces, the world, the cylinder, as well as the correct cone.
that section of geometry which treats associated with the simple properties of right outlines, sectors, plane area, solids bounded by plane surfaces, the world, the cylinder, therefore the right cone.
(math) geometry centered on Euclid's axioms
that section of geometry which treats of quick properties of straight outlines, circles, airplane surface, solids bounded by plane areas, the sphere, the cylinder, therefore the right cone.
