Step-by-step explanation:
Lines can be categorized as natural or artificial. Natural lines are those that occur in nature, such as tree branches, rivers, and cloud formations. These lines are often organic and curving in nature. On the other hand, artificial lines are man-made, like the lines on a road, telephone wires, and building structures.
