Back

G' (-5,-3)

Front

What is a synonym for 'larger' in the context of dilation?

Back

Enlargement

Front

If point A (8, 12) is dilated to point A' (2, 3), what is the scale factor?

Back

1/4

Front

What is a synonym for 'smaller' in the context of dilation?

Back

Reduction

Front

What is the definition of dilation in geometry?

Back

A transformation that produces an image that is the same shape as the original, but is a different size.

Front

How does a scale factor greater than 1 affect a figure during dilation?

Back

It enlarges the figure.

Front

How does a scale factor less than 1 affect a figure during dilation?

Back

It reduces the figure.

Front

What is the center of dilation?

Back

The fixed point in a dilation from which all points are expanded or contracted.

Front

If a figure is dilated by a scale factor of 3, what happens to the distances between points in the figure?

Back

All distances are multiplied by 3.
