8.3C- Dilations

• (x, y) --> (x+ 2, y + 3)

• (x, y) --> (x -2, y - 3)

• (x, y) --> (3x, 3y)

• (x, y) --> (x +1, y +3)

• (x, y) --> (-3x, -3y)

• (x, y) --> (x+4, y)

• (x, y) --> (2x, 2y)

• (x, y) --> (0.3x, 0.3y)

Congruent figures are figures that are the SAME size and the SAME shape.

A dilation produces a congruent figure.

• True

• False

A dilation is which of the following: 

• only an enlargement
• only a reduction
• Either an enlargement or a reduction
• Neither an enlargement or a reduction

• A

• B

• C

• D

A polygon will be dilated on a coordinate plane to create a smaller polygon. The polygon is dilated using the origin as the center of dilation.

Which rule could represent this dilation?

• If a is greater than 1, the image of the polygon is congruent to the polygon.

• If a is between 0 and 1, the image of the polygon is congruent to the polygon.

• If a is greater than 1, the image of the polygon is smaller than the polygon.

• If a is between 0 and 1, the image of the polygon is smaller than the polygon.
