Dilation

Front

What is a dilation?

Back

A dilation is either an enlargement or a reduction of a figure.

Front

What happens to the coordinates of a point when it is dilated by a scale factor of 3?

Back

The coordinates are multiplied by 3.

Front

If point B (0, 4) is dilated by a scale factor of 3, what are the new coordinates?

Back

(0, 12)

Front

What is the scale factor if the point (8, 12) is dilated to (2, 3)?

Back

1/4

Front

If Triangle ABC is dilated using a scale factor of 1/2, what happens to the size of the triangle?

Back

The triangle is reduced to half its original size.

Front

What is the scale factor if a figure is enlarged from a size of 2 to a size of 6?

Back

3 (since 6/2 = 3).

Front

How do you find the new coordinates of a point after dilation?

Back

Multiply the original coordinates by the scale factor.

Front

What is the effect of a scale factor less than 1 on a figure?

Back

It reduces the size of the figure.

Front

What is the effect of a scale factor greater than 1 on a figure?

Back

It enlarges the size of the figure.

Front

If point A (2, 2) is dilated by a scale factor of 1.5, what are the new coordinates?

Back

(3, 3)
