Patterns and numbers in nature
1. Symmetry Fate quality of being made up of exactly similar parts
→ Line oF Symmetry or Mirror line - Is the line that divides a
shape or an object into two equal and symmetrical parts.
bilateral symmetry - Is an arrangement of parts into left
ana right haves on either side of a central axis.
Rotational or Radical Symmetry - A property that a shape has when it looks the same after some rotation
by a partial turn
→ Order of symmetry - Number of positions in which a figure
can be rotated.
→ Angle OF Rotation - Measure of the angle formed when a ay pivots at a center point called vertex or
center
야 rotation.
360°/n
→ order of symmetry
2. Coats - Natural covering on a surface of an object
2.. Stripes - Long, narrow band or strip differ in color or texture
on a surface.
2.2. Spot - small round or roundish mark differ in color or texture
on a surface.
23. Voronoi - Partition of a plane into regions close to each of a
given set of objects.
Fractals - Nonregular geometric shape that has the same degree of non regularity on all scales
2.5. Spirals - Spiral curve emanates from a print, moving farther away as it revolves around the print.
26. Geometry - Properties and relations of print, lines, surfaces, solids, and higher dimensional analogues.
World population - the total number of people of all ages living in all countries across the globe
→ Exponential growth - Pattern across data that shows sharper increases over time.
> A = Pe^rt
A = Population size after it has grown
P = Initial population
e = Euler's number (=. 2. 718)
r = Rate of growth
t = Time
3. Fibonacci Sequence - Is a type of series where each number
is the sum of the two that precede it
