Rigid Geometrical Transformations

A transformation that “turns” a figure about a fixed point at a given angle and a given direction.

• rotation
• translation
• reflection
• dilation

A type of transformation where a figure is “flipped” over a line of symmetry. A reflection produces a mirror image of a figure.

• rotation
• translation
• dilation
• reflection

• right 2, down 5
• right 2, down 9
• left 2, up 9
• left 2, down 9
