Study Notes
Reflection
- Transformation creates a mirror image of a figure or object.
- Artistic creations begin with a motif, defined as any non-empty plane set.
- Repetition of a motif generates a pattern, which is a series of motifs in a plane.
Rotation
- A rotation is an isometric transformation that turns a figure around a fixed angle about a center point.
- Rotations can occur in both clockwise and counterclockwise directions.
Frieze Patterns
- Named by mathematician John Conway, frieze patterns repeat in straight vertical or horizontal lines.
- Common in architecture, fabrics, and wallpaper, there are seven distinct types of frieze patterns.
Dilation
- Dilation changes the size of a figure without altering its shape, resulting in a larger or smaller image.
Glided Reflection
- Combines translation and reflection, known as glide reflection symmetry.
Types of Transformations
- Hop: Involves only translation.
- Slide: Incorporates translation with vertical reflection.
- Jump: Contains translation and horizontal reflection.
- Spinning Hop: Features both translation and 180° rotation.
- Spinning Sidle: Includes translation, glide reflection, and 180° rotation.
- Spinning Jump: Encompasses all symmetries of translation, horizontal and vertical reflections, plus rotations.
Wallpaper Groups
- Formed by adding translation symmetry in a second independent direction, resulting in 17 unique wallpaper groups.
Filipino Arts
- Showcase indigenous fabrics that illustrate patterns and symmetries representative of cultural heritage.
Symmetry
- Derived from Greek "symmetria," meaning to measure together, symmetry is fundamental in geometry.
- Symmetrical objects are the same size and shape with differing orientations.
- Objects without symmetry are termed asymmetric.
Types of Symmetry
- Bilateral Symmetry: Mirror image across two sides.
- Radial Symmetry: Center point with multiple lines of symmetry, exemplified by spider webs.
Patterns in Nature
- Regular forms in nature arise from biological processes, including natural and sexual selection.
- Symmetry in anatomy aids in identifying bodily anomalies.
Tessellation
- A pattern that fills a plane with copies of the same basic shape without gaps or overlaps.
- Regular Tessellation: Comprised of congruent regular polygons.
- Semi-Regular Tessellation: Features multiple polygon types with a consistent vertex arrangement.
- Demi-Regular Tessellation: Edge-to-edge tessellation without consistent vertex types.
Fractals
- Mathematical constructs created by iterating figures, maintaining self-similarity across scales.
- While dilation creates identical figures of different sizes, fractals display similar yet non-identical qualities.
- Example: Ferns exhibit fractal properties as each branch mirrors another.
Iteration
- Refers to the repetition of a process, particularly in mathematics for generating fractals using Iterative Function Systems (IFS).
- Recursion is a specialized form of iteration where starting information applies a rule for generating new information.
