Dilations Flashcard

Front

What is a dilation in geometry?

Back

A dilation is a transformation that alters the size of a figure but not its shape, using a scale factor.

Front

What does a scale factor greater than 1 indicate in a dilation?

Back

It indicates an enlargement of the figure.

Front

What does a scale factor less than 1 indicate in a dilation?

Back

It indicates a reduction of the figure.

Front

What is the scale factor in a dilation if the original figure is reduced to half its size?

Back

The scale factor is 1/2.

Front

How do you express a dilation with a scale factor of 3 algebraically?

Back

(x, y) → (3x, 3y)
