Title: Prezentacja programu PowerPoint
1Hi! My name is Bartek. I would like to tell you
something about symmetry in our life.
What is symmetry? Symmetry is a characteristic of
geometrical shapes, and other objects. We say
that such an object is symmetric, when we applied
symmetry to the object, does not appear to change
it.
2For example my face normal
3My face in right side symmetry
And in left side symmetry
4I want show you the symmetry is around us.
Everywhere in old architecture
5In modern architecture
6In art
7In furniture
8In mosaic
9In love ?
10And sometimes in astronomy
11In mirror ?
12In human body
13In water tile
14In animal body
15In card games
16Bilateral symmetry In bilateral symmetry (also
called plane symmetry), only one plane, called
the sagittal plane, will divide an organism into
roughly mirror image halves (with respect to
external appearance only). Thus there is
approximate reflection symmetry. Often the two
halves can meaningfully be referred to as the
right and left halves, e.g. in the case of an
animal with a main direction of motion in the
plane of symmetry.
17Radial symmetry Radial symmetry These
organisms resemble a pie where several cutting
planes produce roughly identical pieces. An
organism with radial symmetry exhibits no left or
right sides. They have a top and a bottom (dorsal
and ventral surface) only.
18Its end of my presentation. I would thank you
for patience and consistency. In this
presentation I used internet and computer
programs.
