FLASHCARD QUESTION

Front

What is a dilation in geometry?

Back

A dilation is a transformation that alters the size of a figure but not its shape, using a scale factor.

2.

FLASHCARD QUESTION

Front

What does a scale factor greater than 1 indicate in a dilation?

Back

It indicates an enlargement of the figure.

3.

FLASHCARD QUESTION

Front

What does a scale factor less than 1 indicate in a dilation?

Back

It indicates a reduction of the figure.

4.

FLASHCARD QUESTION

Front

How is a dilation represented algebraically?

Back

A dilation can be represented as (x, y) → (kx, ky), where k is the scale factor.

5.

FLASHCARD QUESTION

Front

If the scale factor is 3, what happens to the coordinates of a point (2, 4) after dilation?

Back

The new coordinates will be (6, 12) because (2*3, 4*3) = (6, 12).

6.

FLASHCARD QUESTION

Front

What is the difference between enlargement and reduction in dilation?

Back

Enlargement increases the size of the figure (scale factor > 1), while reduction decreases the size (scale factor < 1).

7.

FLASHCARD QUESTION

Front

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

Back

The figure remains unchanged.
