Dilations Intro

Front

What is a dilation in geometry?

Back

A transformation that alters the size of a figure but not its shape.

Front

What does a scale factor (SF) greater than 1 indicate?

Back

An enlargement of the figure.

Front

What does a scale factor (SF) less than 1 indicate?

Back

A reduction of the figure.

Front

If the scale factor is 2.5, what type of dilation is it?

Back

Enlargement.

Front

What is the term for a figure that is produced larger by a dilation?

Back

Enlargement.

Front

What is the center of dilation?

Back

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

Front

If an image is reduced, what can be said about its dimensions?

Back

The dimensions of the image are smaller than the original.

Front

What happens to the angles of a figure during a dilation?

Back

The angles remain the same.

Front

What is the effect of a dilation on parallel lines?

Back

Parallel lines remain parallel after dilation.

Front

If a figure is dilated with a scale factor of 1, what happens to the figure?

Back

The figure remains unchanged.
