Vocabulary Transformation – An operation that maps an original geometric figure onto a new figure Image – The resulting figure after a transformation Translation – When you SLIDE a figure from one position to another without turning it Reflection – When you FLIP a figure over a line. Line of Symmetry – The line you flip a figure over in a reflection

Taking a Closer Look Translation Reflection

Notes Translation Reflection Called a SLIDE Image is the same shape and the same size as original figure Orientation is the same as the original figure Called a FLIP Figures are mirror images of each other Image is the same shape and same size as original figure Orientation is different from the original figure

NOTES - TRANSLATIONS When translating a figure, every point of the original figure is moved the SAME DISTANCE and the SAME DIRECTION
