Dilations Practice

Front

What is a dilation in geometry?

Back

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

Front

What does a scale factor of 3 mean in a dilation?

Back

It means that every point of the figure is moved away from the center of dilation by a distance three times its original distance.

Front

If a figure is dilated by a scale factor of 2, what happens to its size?

Back

The figure is enlarged to twice its original size.

Front

What is the center of dilation?

Back

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

Front

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

Back

The figure is reduced in size.

Front

Is a dilation always an enlargement?

Back

No, a dilation can be either an enlargement or a reduction.

Front

What does it mean for two figures to be congruent?

Back

They have the same shape and size.

Front

If a dilation produces a figure that is not congruent, what does that imply?

Back

The figures are not the same size, indicating a change in dimensions.

Front

What is the result of dilating a point at (2, 3) by a scale factor of 3?

Back

The new coordinates will be (6, 9).

Front

If a figure is dilated by a scale factor of 1/2, what happens to its dimensions?

Back

The dimensions of the figure are halved.
