2. Geometry in
Photography
 The reason that 45 degree lighting
is so important is that it’s the
perfect angle to create modeling
on the human form.
Subject  The term modeling refers to
showing three dimensionality
through the use of light.
 When you have light coming
Li
from where the camera is, that
gh
tin
three dimensionality is lost
g
because shadows aren’t seen on
the face.
 Put the light off the camera and
you get shadows, which gives you
3D, and 45 degrees is the perfect
angle to maximize this effect.

Stairs : inclined at 60o,
with each stair at 90o.
Semicircles in
30o Cycles
120o 30o
A Simple cloth hanger has 2
x 30o angles + 1 x 120o angle
= 180o angle.

4. Geometry in
Architecture
• Arches are used to withstand
maximum weight.
• Structural designs to
withstand forces of nature

6.  The shortest path between two points
is a straight line.
 The two sides of Roads are always
parallel to each other

Racing bikes are made using best
geometry to give maximum efficiency.

12. Geometry in Daily Life
• Geometry is considered an important field of study because of its
applications in daily life.
• For example, a sports car move in a circular path and it applies the
concepts of geometry.
• Stairs are made in your homes inclined at 60o, with each stair
designed at 90 degrees.
• A Simple cloth hanger has 2 x 30o angles + 1 x 120o angle = 180o
angle.
• A ceiling fan has its 3 blades at 120o angles to make 360o while in
motion.
• Any object when thrown at 45o angle, covers maximum distance.
• In addition, geometrical shapes are also used by the artists. The most
interesting example is that nature speaks of geometry and you can
see shapes in all things of nature.

What is so special …
•The Ridley frames are built with
the longest head tubes in the
industry.
•The stem is sitting directly above
the head tube, translation;
comfort, stability, control.
•In addition to longer head tubes,
Ridley has revolutionized frame
geometry by introducing the first
1.5inch bottom headset.
•This enables maintaining light
low weight on all their frames

14. Geometry in Daily Life
 We need not be lost anywhere in this great universe. We can
go to any place and come back to the place of origin. The
location concept is a geometrical concept. Even a sailor
amid sea and a pilot in the air uses geometrical ideas to
locate himself and where he is heading.
 Designing our house, School, town planning,roads, bridges,
surveying are the products of geometry.
 Astronomy,Dynamics,Statics,Spacial movemnts of
Satellites and plannets , knwoledge of the sun ,stars,milky
way and universe are the extended thought of the geometry.
