Dilations and Scale Factor

Front

What is the number you multiply by the sides to create a similar figure?

Back

Scale Factor

Front

Does a dilation produce a similar figure? (True/False)

Back

True

Front

Which is an example of an enlargement? (k = 1/2, k = 1, 2:3, 2.5)

Back

2.5

Front

Are the following similar? Why or why not? (Yes, because the corresponding angles are congruent., No, the numbers are even, No, the sides are 2 times larger, but the width is the same.)

Back

No, the sides are 2 times larger, but the width is the same.

Front

Which is an example of a reduction? (k = 1/2, k = 1, 3:2, 250%)

Back

k = 1/2

Front

What is a dilation in geometry?

Back

A transformation that produces a figure similar to the original by enlarging or reducing it.

Front

What does a scale factor greater than 1 indicate?

Back

An enlargement of the figure.

Front

What does a scale factor less than 1 indicate?

Back

A reduction of the figure.

Front

If a triangle has sides of 3, 4, and 5, what are the sides after a dilation with a scale factor of 2?

Back

6, 8, and 10.

Front

What are corresponding angles in similar figures?

Back

Angles that are in the same position in different similar figures.
