Math 2 - Transformations Review

A dilation is

• Has a central point that stays fixed and everything else turns 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 slides an object a certain distance

A reflection

• Has a central point that stays fixed and everything else turns 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 slides an object a certain distance

A translation

• Has a central point that stays fixed and everything else turns 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 slides an object a certain distance.

A rotation

• Has a central point that stays fixed and everything else turns 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 slides an object a certain distance
