Study Notes
- , or diagonal.
Characteristics of Lines
- Horizontal lines suggest calm and stability, often reminiscent of a horizon line in nature.
- Vertical lines give the impression of defying gravity, rising to great heights from an earthly perspective, as seen in skyscrapers.
- Diagonal lines are dynamic and restless, conveying energy, spontaneity, and whimsicality, such as in Jacob Lawrence's tempera painting of slaves.
Defining Shapes
- Shapes are distinct areas on a 2D surface created in various ways
- One way is by connecting a line to itself, enclosing an area
- Intersecting lines can also enclose an area, forming a shape
- Shapes can be created by surrounding an area with other shapes, giving it distinct boundaries
- Value, color, or texture can be used to distinguish an area from its surroundings, making it a shape
Shape Characteristics
- A shape's type is determined by its outer edge.
- Shapes can be classified into two main categories: rectilinear and curvilinear.
- Rectilinear shapes have straight edges and angular corners.
- Curvilinear shapes have curving edges.
Geometric Shapes
- Both rectilinear and curvilinear shapes can be described as geometric.
- Geometric shapes are derived from mathematical formulas.
- Geometric shapes are rendered with great precision.
Non-Objective Geometric Shapes
- Pure geometric shapes are labeled non-objective.
- Non-objective shapes are not derived from visible reality.
- Examples of non-objective shapes include circles, spheres, and cones.
Types of Lines
- There are two types of lines: outline and contour lines.
- An outline is an actual line that defines a boundary or outer edge of an object or a figure.
- A contour line is not an actual line but an edge that is perceived where a three-dimensional form curves away from the viewer.
Directionality of Lines
- Motion is implied in the definition of line as a moving point.
- Lines can be classified into three directions: vertical, horizontal, and diagonal.
- Horizontal lines suggest calm and stability, like a horizon line in nature.
- Vertical lines seem to defy gravity, rising from the earth-bound perspective to seemingly limitless heights, as seen in skyscrapers.
- Diagonal lines convey energy, spontaneity, and whimsicality, as seen in Jacob Lawrence's tempera painting of slaves.
Shapes
- Shapes are distinct areas on a two-dimensional surface created in several ways.
- Shapes can be created by connecting a line to itself, by intersecting lines, by surrounding an area with shapes, or by using value, color, or texture to distinguish areas.
- The outer edge of a shape characterizes its type, which can be rectilinear (with straight edges and angular corners) or curvilinear (with curving edges).
- Both rectilinear and curvilinear shapes can be geometric, derived from mathematical formulas and rendered with precision.
- Pure geometric shapes, such as circles, spheres, and cones, are non-objective and not derived from visible reality.
- Amorphous or shapeless shapes are the result of irregular pooling of poured paint rather than a deliberately created shape.

Shapes and Cultural Icons
- Some shapes have become instantly recognizable and evoke specific associations.
- These shapes are never mistaken for anything else, having a unique identity.
- They can be considered cultural icons, similar to icons in digital interfaces, such as a folder icon signifying access to a list of files.
- Certain shapes possess symbolic meaning that transcends their literal configuration.
