Front

If a figure is dilated with a scale factor of 0.5, what happens to its size?

Back

It reduces to half its size

Front

Back

Front

Does the image show a Dilation?

Back

Yes

Front

What is a dilation in geometry?

Back

A transformation that alters the size of a figure but keeps its shape.

Front

What is the scale factor in a dilation?

Back

The ratio of the size of the image to the size of the original figure.

Front

If the scale factor is greater than 1, what happens to the figure?

Back

The figure enlarges.

Front

If the scale factor is less than 1, what happens to the figure?

Back

The figure reduces in size.

Front

What is the center of dilation?

Back

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