intricate waves across
the oceans; sand dunes on deserts; formation
of typhoon; water drop with ripple and others.
Other patterns in nature can also be seen in the ball
of mackerel, the v-formation of geese in the sky and
the tornado formation of starlings.
okay
a sense of harmonious and
beautiful proportion of balance or an object is
invariant to any various transformations
(reflection, rotation or scaling.)
SYMMETRY

into approximately mirror image of each other
along the midline.
Bilateral Symmetry:
Vertical Symmetry
Bilateral Symmetry:
Radial symmetry suits
organism like _______ whose adults do not move and jellyfish(dihedral-D4 symmetry).
sea anemones
A five-fold
symmetry is found in the ______, the group in
which includes starfish (dihedral-D5 symmetry), sea
urchins and sea lilies.
echinoderms
a
symmetry around a fixed point known as the center
Radial Symmetry ( or rotational symmetry ):
Radial Symmetry ( or rotational symmetry )
it can be classified as either_____
cyclic or dihedral.
a curve or geometric figure, each part
of which has the same statistical character as the
whole.
fractals
A fractal is a ______found in
nature.
never-ending pattern
The exact same shape is replicated in a
process called ______
“self similarity.”
A logarithmic spiral or growth spiral is a
self-similar spiral curve which often appears in
nature.
Spirals
Spiral was first describe by ____and
was later investigated by ________.
Rene Descartes
Jacob Bernoulli
is
a curved pattern that focuses on a center point and
a series of circular shapes that revolve around it.
spiral
Examples of spirals are_____
pine cones, pineapples,
hurricanes.
The reason for why ____ use a spiral
form is because they are constantly trying to grow
but stay secure.
plants
is a series of numbers
where a number is found by adding up the two numbers
before it.
FIBONACCI SEQUENCE
FIBONACCI SEQUENCE FORMULA
Xn = Xn−1 + Xn−2
Named after Fibonacci, also known as _____
Leonardo
of Pisa or Leonardo Pisano,
Fibonacci numbers were
first introduced in his _____
Liber Abbaci (Book of Calculation)
in 1202.
One of the book’s exercises which is written like
this “A man put a pair of rabbits in a place surrounded
on all sides by a wall. How many pairs of rabbits are
produced from that pair in a year, if it supposed that
every month each pair produces a new pair, which from
the second month onwards becomes productive?” This
is best understood in this diagram:
THE HABBIT RABBIT
The sequence encountered in the rabbit problem 1, 1,
2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, …. is called
the ______ and its terms the_______
Fibonacci sequence
Fibonacci
numbers
Fibonacci
discovered a sequence of numbers that created an
interesting numbers that created an interesting pattern
the sequence 1, 1, 2, 3, 5, 8, 13, 21, 34… each number is
obtained by adding the last two numbers of the
sequence forms what is known as _______ a
perfect rectangle.
golden rectangle
