The standard geometric shapes are found in Euclidean space, defined by Euclid's postulate that two parallel lines never intersect. Those that are defined by straight lines, one dimensional objects, are referred to as polygons, where poly refers to the many sides. Examples are squares, rectangles, and triangles. Those that are defined by curves are such things as circles, ovals, etc.
