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 is the scale factor in a dilation?

Back

The scale factor is a number that scales, or multiplies, the coordinates of a figure during a dilation.

Front

What happens to a figure when the scale factor is greater than 1?

Back

The figure is enlarged.

Front

What happens to a figure when the scale factor is less than 1?

Back

The figure is reduced.

Front

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

Back

(x, y) → (2x, 2y)
