Transformations
|
Changes in position and size of a shape. Translation (or slide) is the movement of a shape so that all its points move the same distance in the same direction.
Rotation (or turn) is the movement of a shape when it is turned through an angle about a point in a plane.
Reflection (or flip) is the movement of a shape when it is reflected (or flipped) over a line in the plane of the figure.
Dilation is an enlargement or reduction of a shape in which all the linear measures are multiplied by the same number (called the scale factor).
