Answer:
The answer is "Lines."
Explanation:
A "line" is considered one of the fundamental elements when it comes to "art." It comes in different forms such as<em> "straight lines," "curved lines," "diagonal lines," "spiral lines," etc.</em>
When it comes to certain situations such as <em>"creating shapes,</em>" the lines are used to define the edge or boundary of something. As a boundary, the line functions to circumscribe the shape (such as a circle).
