Example If the figure on the right is moved in ways , , or
, choose the ways that do not change the shape of
the figure.
Class Notes
Sliding (changes, does not change) the figure.
, Flipping sideways reverses the figure left to right.
, , flipping upside down, reverses the figure top to bottom.
, , , , , and show the figure being . When rotated in
ways and , the figure becomes:
Therefore, the figure does not change shape when moved in ways and .
Try It Again The figure is moved in ways , and . Find which way
(slide, flip, or rotate) they each correspond to.
