1. SPIDERS WEB
When spiders web unite, they
can tie up the lion….

SEMESTER- VI
2. WHAT ARE SPIDER
WEBS AND WHY ARE
THE MADE?
➢Spider webs are made from
spider silk , most versatile
material on the earth.
➢Actually they are the protein also
known as spinnerets .
➢Spider webs are mostly use for
shelter, courtship and all kinds of
ways to trap prey.
3. First it connects two end
points like two branches
with silk thread, forming a
bridge
It then releases a lose
thread from its center
It adds a new thread.
HOW ARE SPIDERS WEB MADE?
4. It joins three points to form a
frame
Pulling it to form a Y shape.
A model is created
5. Then it releases radial thread to
become strong enough.
Finally from the center it spins spirally
completing the web.
The study shows that the radial angle
of orientation 12.7 degree with 5mm
distance for the spirals mesh size
6. Is spider using
fibonacci sequence??
➢ Spider weaves structure together making sheets,
tangling and funnel webs.
➢ The Fibonacci sequence allows for the web to be
strengthened and also remain compact.
➢ Nature uses Fibonacci sequence to
accommodate growth and length of the potential
web.
7. What is Fibonacci series ?
➢ A series of numbers in which each number is sum of two
preceding numbers is known as Fibonacci series
➢0,1,1,2,3,5,8,13,21…
What is golden ratio?
1.In mathematics, two quantities are in the golden ratio if their ratio is the
same as the ratio of their sum to the larger of the two quantities.
2.The golden ratio is a mathematical constant approximately 1.6180339887.
The golden ratio is also known as the most aesthetic ratio between the two
sides of a rectangle.

9. What is the relation
between Fibonacci
sequence and golden
ratio?
+ The ratios of sequential Fibonacci
numbers (2/1, 3/2, 5/3, etc.) approach
the golden ratio. In fact, the higher the
Fibonacci numbers, the closer their
relationship is to 1.618. The golden
ratio is sometimes called the "divine
proportion," because of its frequency in
the natural world.
10. The golden triangle is an isosceles
triangle with the angles of 72
degree -72 degree-36 degree .
If you divide the long side by the
short side you get Phi or the
golden ratio.
This triangle is also inherent in the
creation of pentagon.
By dividing in half the long side of
the triangle you will find a vertex
point of a 36 degree – 36 degree-
108 degree triangle.
The vertex just found is the center
point for swinging arc.
By repeating the process of
creating a newer, smaller triangle
angle and again swinging the new
arc, the finalized infinite spiral is
created.
