K&K Dilation and Translation

Front

What does a dilation produce?

Back

A similar figure.

Front

When the scale factor of a dilation is less than one, what type of dilation is it?

Back

Reduction.

Front

Which term means translation?

Back

Slide.

Front

What is the algebraic rule for a dilation with a scale factor of 2?

Back

(2x, 2y).

Front

What is the rule for the dilation that transforms (x,y) to (2x,2y)?

Back

(x,y)→(2x,2y).

Front

What is the effect of a dilation with a scale factor greater than 1?

Back

It enlarges the figure.

Front

What is the effect of a dilation with a scale factor of 1?

Back

The figure remains the same size.

Front

What is the geometric transformation that moves a figure without changing its size or shape?

Back

Translation.

Front

If a figure is translated 3 units to the right and 2 units up, what is the algebraic representation?

Back

(x,y)→(x+3,y+2).

Front

What is the difference between dilation and translation?

Back

Dilation changes the size of the figure; translation moves it without changing size.
