PRESENTATION OUTLINE
TRANSFORMATION
- Moving a shape so that it is in a different position, but still has the same size, area, angles and line lengths.
- A real world example is lockers
ISOMETRY
- It means that at the end of the transformation the figure will have the exact same measurements and angles
- A real world example would be blocks
TRANSLATION
- Moving a shape, without rotating or flipping it.
- A real worl example would be a bus.
COMPOSITION OF TRANSFORMATIONS
- 2 or more transformations will be performed on one object
- A real world example would be a kaleidoscope
REFLECTION
- Every point is the same distance from the central line
- A real world example would be a mirror
ROTATION
- A circular movement.
- A real world example would be a ball rolling
SYMMETRY
- one shape becomes exactly like another if you flip, slide or turn it.
- A real world example would be a square
REFLECTIONAL SYMMETRY
- A type of symmetry where one half is the reflection of the other half.
- An example would be a butterfly
ROTATIONAL SYMMETRY
- A type of symmetry where one half is the reflection of the other half.
- A real world example would be a dartboard
POINT SYMMETRY
- It looks the same Upside Down
- A real world example would be playing cards
LINE SYMMETRY
- Another name for reflection symmetry. One half is the reflection of the other half.
- A real world example would be a sun flower
DIALATION
- To resize something
- A real world example would be your eye
GLIDE REFLECTION
- transformation involving a translation and a reflection in a line parallel to the translation.
- A real world example would be a drawing
