    Symmetry

    Definition

    "When we divide a shape or figure into two parts of equal shape and size, we call the shape or figure symmetrical".
    The phenomenon is called as "symmetry".

    Example:

    symmetryandpatterns

    In the above figure, all the shapes given are symmetrical.
    In each of the figure, a line is dividing the figure into two equal halves.
    The line which divides a shape or figure into two identical halves is called the "Line of Symmetry".
    The shapes can have vertical axes of symmetry, horizontal axes of symmetry or both.
    Examples:

    Vertical Axis Of Symmetry

    Horizontal Axis Of Symmetry

    Symmetry In Plane Shapes

    Symmetry can also be seen in plane shapes.
    A plane shape is said to be symmetrical about a line, if the line divides the shape into two equal halves.
    Some shapes have one line of symmetry, while some have two or even more lines.
    There are also some shapes which are not symmetrical at all.
    Let us observe the line of symmetry in shapes.

Tessellation

"A collection of plane or simple figures that fills the plane to form a pattern without leaving any space or overlaps in between".

Examples:

symmetryandpatterns

We can see that the shapes fit together to form a pattern.
This is called "Tessellation".

REFLECTION

"The image of an object or a shape corresponding in appearance is known as reflection".
Reflection from a mirror throws back or gives back the image shown.
Reflecting an object produces its mirror image.
Examples:

SLIDES, FLIPS, AND TURNS

SLIDE

"A slide takes place when a shape moves in one direction from one place to another".

FLIP

"A flip takes place when a shape is flipped across a line and faces the opposite direction".

symmetryandpatterns

TURN

"A turn takes place when a shape is turned through an angle".

    Patterns

    Definition

    "The series or a sequence of repeated objects, sounds, or numbers is known as patterns".

  • A pattern can have repeated decorative designs.
  • They can be regular form or order in which a series of things occurs.
  • Patterns can be found in nature and in numbers.
    PATTERNS IN NATURE

    It is a beautiful observation to see patterns in nature.

  • Cut a kiwi fruit and see the patterns formed
  • Look at a peacock and see the patterns.
  • Look at a sunflower and see the patterns formed beautifully.
    PATTERNS IN NUMBERS

    Numbers also reflect beautiful patterns.
