SHAPES & FORMS - GEOMETIC & ORGANIC Shape: Two-dimensional (2-D) - length and width - circles, squares, rectangles, triangles (geometric) and odd (organic) shapes formed by a line that connects to itself and encloses a space. Positive space is the inside of the shape. Negative space is the empty area outside a shape.
