A reflection

• Has a central point that stays fixed and everything else moves around that point

• a transformation that changes the size of a figure

• a transformation in which the preimage is flipped across a line

• a function that moves an object a certain distance. The object is not altered in any other way.

• (x,y) -> (2x, 2y)

• (x,y) -> (0.5x, 0.5y)

• (x,y) -> (0.4x, 0.4y)

Reflect the image across x = -3

• I' (-1,-1) P' (-2,2) S' (-4,1) W' (-4,3)

• I' (-1,-1) P' (-2,-2) S' (-4,1) W' (-4,3)

• I' (-1,-1) P' (-2,-2) S' (-4,-1) W' (-4,3)

• I' (-1,-1) P' (-2,-2) S' (-4,1) W' (-4,-3)

Reflect the image across y = -x

• A' (1,-3) J' (-3,-4) T' (2,5) S' (-2,4)

• A (1,-3) J (3,-4) T (2,5) S (-2,4)

• A' (1,-3) J' (3,-4) T' (2,-5) S' (-2,-4)

• A' (1,-3) J (3,-4) T' (2,5) S' (-2,-4)
