Glide reflection
The combination of a reflection in a line and a translation along
that line.
Orientation
Orientation refers to the arrangment of points relative to one another after a transformation
has occured.
Isometry
An isometry is a transformation that preserves length.
A direct isometry preserves orientation.
Opposite isometry changes the order clockwise or counter clockwise.
Invariant
A figure or property that remains unchanged under a transformation of the plane is
referred to as invariant. Meaning no variations(changes) have occured.
Question
word that means it preserves the same length?
ok. how else could you describe "glide reflection"? is there an example?
ReplyDeletefor orientation, is there a specific arrangement of points that you are referring to?
