What is the technical difference between a SHAPE and a FORM in two-dimensional art? Chose the best definition from the choices below: Diagram A: Diagram B Group of answer choices A "shape" is by definition two-dimensional in appearance; a "form" in two-dimensional art is a shape that is modeled or shaded so as to appear three-dimensional. Diagram A is a "form." Diagram B is a "shape". A shape is strictly speaking any a geometrical object (line, square, rectangle) whereas a form is irregular in outline. Neither A nor B is a "form"; both are "shapes." A "Shape" by definition has no color; a "Form" is a colored shape. Both A and B are therefore "forms". A "shape" has a sharp edge or contour, a "form" has a fuzzy edge or contour (so that you can't tell where the edge ends). Neither diagram A nor diagram B represents a form; both are shapes
