Intro to Scale Factor Dilations

Front

What happens to a figure when the scale factor is less than one?

Back

The figure undergoes a reduction.

Front

What is the term for a larger figure produced by a dilation?

Back

Enlargement.

Front

What is the image of the point B (-10,-6) under a dilation with center at the origin and scale factor k = 1/2?

Back

(-5,-3).

Front

Does the image show a Dilation? If yes, did the image enlarge or reduce?

Back

Yes, it enlarged.

Front

What are the coordinates of point A' after a dilation of scale factor 1/2 for triangle CAT with A (6,10)?

Back

(3,5).

Front

Define scale factor in the context of dilations.

Back

The scale factor is a number that describes how much a figure is enlarged or reduced during a dilation.

Front

What is a dilation in geometry?

Back

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

Front

If a scale factor is greater than one, what type of transformation occurs?

Back

An enlargement.

Front

What is the center of dilation?

Back

The fixed point in a dilation from which all points are expanded or contracted.

Front

How do you calculate the coordinates of a dilated point?

Back

Multiply the original coordinates by the scale factor.
