Translation
Translation
In Geometry, "Translation" simply means Moving ...
... without rotating, resizing or anything else, just moving.
. Every translation has a direction and a distance.
To Translate a shape:
| | Every point of the shape must move:
- the same distance
- in the same direction.
Writing it out
Example: if we want to say that the shape gets moved 30 Units in the "X" direction, and 40 Units in the "Y" direction, we can write:
This says "all the x and y coordinates will become x+30 and y+40" |  |
Rotation
"Rotation" means turning around a center:
To rotate an object means to turn it around. Every rotation
has a center and an angle.
To reflect an object means to produce its mirror image.
Every reflection has a mirror line. A reflection of an "R" is a backwards "R".
A glide reflection combines a reflection with a
translation along the direction of the mirror line. Glide reflections are the
only type of symmetry that involve more than one step.
