Step-by-step explanation:
The visual element of art that is not mentioned in the options is angle. The visual elements of art include color, shape, texture, and angle. Color refers to the different hues used in the artwork, shape pertains to the form or outline of an object, and texture is the visual or tactile quality of the artwork. Angle, on the other hand, is not typically considered a visual element of art.
