2. Inorganic lines

11. Organic lines
• asymmetrical and curved
• they don’t follow the shape of any geometrical figure.
• these lines are found in nature
• are irregular and these lines are always used to draw
nature, hence having the term "organic" or "nature"

14. Inorganic lines
• complete opposite of organic lines
• they are regular and follow a geometrical pattern and
geometrical shape
• they are rigid and follow rules
• these lines are used when drawing man-made
structures.
