Dilations & Similar Triangles

Front

Dilate the figure by a scale factor of 3 with the origin as the center of dilation. What are the coordinates of the image for A(3,3) B(6,6) C(9,3)?

Back

A'(9,9) B'(18,18) C'(27,9)

Front

A dilation always produces a similar figure. Similar figures have the same ______ but different ______.

Back

shape; sizes

Front

Determine the correct algebraic representation of the similar figures:

(x, y) -> (.5x, .5y)

,

(x, y) -> (2x, 2y)

,

(x, y) -> (x + 2, y + 2)

,

(x, y) -> (x - .5, y - .5)

Back

(x, y) -> (2x, 2y)

Front
