These are flips, slides, turns, and enlargements/reductions. TRANSFORMATIONS Transformations are line reflections, translations, rotations, and dilations. These are flips, slides, turns, and enlargements/reductions.

LINE REFLECTIONS Line reflections “FLIP” a figure. A reflection maps every point of the pre-image to an image point over the line of reflection that is the perpendicular bisector of the segment connecting the pre-image and image point. Line reflections are RIGID MOTIONS(transformations that keep the same size and angle measure). There are 4 simple rules to follow when reflecting over 4 lines in the coordinate plane, which we will be looking at on next 4 slides.

Graphically - You will now need graph paper. A reflection across the x-axis of point P(2,3):

A reflection across the y-axis A reflection across the y-axis of P(2,3):

A reflection across y=x A reflection across the line y=x of P(-3,2):

A reflection across the line y=-x A reflection across y=-x of P(3,2):
