"Two-dimensional" refers to objects or shapes that have only two measurements: length and width. This means they exist on a flat surface and do not have any depth. Common examples of two-dimensional shapes include squares, circles, and triangles. You can easily draw these shapes on a piece of paper, and they can be represented in art, design, and mathematics. In contrast to three-dimensional objects, which have depth and can be viewed from multiple angles, two-dimensional items appear flat. For instance, a painting on a wall is two-dimensional, while a sculpture is three-dimensional. Understanding two-dimensional concepts is essential in fields like graphic design and geometry.
