Lines are one of the basic elements of art. There are 5 types of lines - vertical, horizontal, diagonal, zigzag and curved. Vertical lines run straight up and down, horizontal lines run straight left to right in a parallel fashion, and diagonal lines slant in any direction other than vertical or horizontal. Zigzag lines form a series of joined diagonal lines, while curved lines bend and change direction gradually. Lines can also be organic, taking on irregular, asymmetrical curves found in nature, or inorganic, following rigid geometrical patterns used in man-made structures.

1. Elements of Art:
Lines

2. Lines
•one of the many elements of art
and are regarded as the most basic
among elements of art.

3. 5 Types of Lines
1. vertical lines
2. horizontal lines
3. diagonal lines
4. zigzag lines
5. curved lines

4. Vertical lines
• straight up and down lines
that are moving in space
without an slant and are
perpendicular to
horizontal lines

5. Horizontal lines
straight lines parallel to
the horizon that move
from left to right.

6. Diagonal lines
straight lines that slant
in any direction except
horizontal or vertical.

7. Zigzag lines
 series of diagonal lines
joined at ends.

8. Curved lines
lines that bend and
change direction
gradually

10. 2 Kinds of Lines
1. Organic lines
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.
