Compare with Definitions

Curve

In mathematics, a curve (also called a curved line in older texts) is an object similar to a line, but that does not have to be straight. Intuitively, a curve may be thought of as the trace left by a moving point.

Surface

A surface, as the term is most generally used, is the outermost or uppermost layer of a physical object or space. It is the portion or region of the object that can first be perceived by an observer using the senses of sight and touch, and is the portion with which other materials first interact.

Curve

A line that deviates from straightness in a smooth, continuous fashion.

Surface

The outside part or uppermost layer of something

Curve

A surface that deviates from planarity in a smooth, continuous fashion.
