Study Notes
Nature of Mathematics
- Movement of figures on a coordinate plane results in a transformation, changing the figure's position.
- Original shapes are labeled with capital letters; transformed shapes use the same letters with a "prime symbol."
Patterns and Numbers in Nature
- Patterns in nature reflect visible regularities and are crucial for understanding natural processes.
- Mathematical patterns can include numerical, visual, logic, and word patterns, with number patterns being most common.
Transformation Types
-
Translation (Slide):
- Moves each point of a figure the same distance and direction.
- Size, shape, and direction remain unchanged.
- Example: Movement of jumping animals like kangaroos and frogs.
-
Reflection (Flip):
- Flips a figure over a line (line of reflection).
- The original figure and its reflection have identical shapes and sizes but face opposite directions.
- Example: Light reflection.
-
Rotation (Turn):
- Rotates a figure around a fixed point, termed the center of rotation.
- The shape and size of the figure stay constant, but orientation changes based on the angle of rotation.
Tessellation
- Defined as a repeating pattern made with regular polygons with no gaps or overlaps.
- Each vertex in a tessellated shape remains consistent, creating a visual illusion.
- Examples of tessellations in nature include beehives, pineapples, and turtle shells.
- M.C. Escher is notable for his use of tessellations in art.
