Dilations

Front

What happens to angles after dilations?

Back

Angles remain congruent after dilations.

Front

Does a dilation produce a congruent figure?

Back

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

Front

If angle A corresponds to angle P, what can we say about their measures?

Back

Angle A and angle P have the same measure.

Front

What is the result of an enlargement in a dilation?

Back

An enlargement increases the size of the figure.

Front

What is the result of a reduction in a dilation?

Back

A reduction decreases the size of the figure.

Front

In a dilation, what is the relationship between corresponding sides of similar figures?

Back

Corresponding sides are proportional.

Front

What is the scale factor in a dilation?

Back

The scale factor is the ratio of the lengths of corresponding sides of the original figure to the dilated figure.

Front

If line CB corresponds with line RQ, what can we infer about their lengths?

Back

Line CB and line RQ are proportional in length.

Front

What does it mean for two figures to be similar?

Back

Two figures are similar if they have the same shape but not necessarily the same size.

Front

What is the effect of a scale factor greater than 1 in a dilation?

Back

A scale factor greater than 1 results in an enlargement.
