Transformation
|
A transformation is a one-to-one correspondence between two sets of points.
|
|
|
Translation
|
A translation is the composite of two successive reflections through parallel lines.
|
|
|
Rotation
|
A rotation is the composite of two successive reflection through intersecting lines
|
|
|
Reflection
|
The reflection of point P through line l is P itself if P lies on l. Otherwise, it is the point P' such that l is the perpendicular bisection of PP'
|
|
|
Isometry
|
An isometry is a transformation that preserves distance and angle measure.
|
|
|
Construction 8
|
To reflect a point through a line.
|
|
|
Congruent ( In terms of a isometry)
|
Two figures are congruent if there is an isometry such that one figure is the image of the other.
|
|
|
Glide Reflection
|
A glide reflection is the composite of a translation and a reflection in a line parallel to the direction of the translation.
|
|
|
Rotation Symmetry
|
A figure has rotation symmetry with respect to a point iff it coincides with its rotation image through less than 360º about the point.
|
|
|
Reflection (line) Symmetry
|
A figure has reflection (line) symmetry with respect to a line iff it coincides with its reflection image through the line.
|
|
|
Translation Symmetry
|
A pattern has translation symmetry iff it coincides with a translation image.
|
|
|
Dilation
|
Enlarging or reducing an image.
