Back

2

Front

A dilation is which of the following?

Back

Either an enlargement or a reduction

Front

The point (8, 12) was dilated to become point (2, 3). What was the scale factor?

Back

1/4

Front

Dilate Point B by a scale factor of 3: What is the new coordinate?

Back

(0, 12)

Front

What is a dilation in geometry?

Back

A transformation that alters the size of a figure but not its shape.

Front

If a point is dilated by a scale factor greater than 1, what happens to the point?

Back

The point moves away from the origin, enlarging the figure.

Front

If a point is dilated by a scale factor less than 1, what happens to the point?

Back

The point moves closer to the origin, reducing the figure.

Front

What is the formula for dilating a point (x, y) by a scale factor k?

Back

(kx, ky)

Front

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

Back

The figure remains unchanged.
