Performance Final Dilation Review

Front

What is a dilation in geometry?

Back

A transformation that alters the size of a figure but not its shape, resulting in a similar figure.

Front

Does a dilation produce a congruent figure?

Back

False, a dilation produces a similar figure, not a congruent one.

Front

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

Back

The figure undergoes an enlargement.

Front

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

Back

The figure undergoes a reduction.

Front

What is the scale factor in a dilation?

Back

The ratio of the length of a side of the image to the length of the corresponding side of the original figure.

Front

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

Back

All dimensions of the figure are doubled.

Front

If a figure is dilated by a scale factor of 0.5, what happens to its dimensions?

Back

All dimensions of the figure are halved.

Front

What is the relationship between similar figures?

Back

Similar figures have the same shape but may differ in size.

Front

How do you find a missing side in similar figures?

Back

Use the ratio of corresponding sides to set up a proportion.

Front

What is the effect of a dilation on angles?

Back

Dilation does not change the measures of angles; they remain congruent.
