Dilations and Translations

Front

What math process is used in a translation?

Back

Addition/Subtraction

Front

In a translation, if the image is moved left 5, what does this mean?

Back

The image is shifted 5 units to the left on the coordinate plane.

Front

What is the correct scale factor for a dilation that doubles the size of a figure?

Back

2

Front

What is a dilation?

Back

A transformation that can either enlarge or reduce a figure.

Front

If a figure is dilated by a scale factor of 3, what happens to its dimensions?

Back

All dimensions are multiplied by 3.

Front

What are the coordinates of point A(3,3) after a dilation by a scale factor of 3?

Back

A'(9,9)

Front

What are the coordinates of point B(6,6) after a dilation by a scale factor of 3?

Back

B'(18,18)

Front

What are the coordinates of point C(9,3) after a dilation by a scale factor of 3?

Back

C'(27,9)

Front

In a translation, moving right 5 means what?

Back

The image is shifted 5 units to the right on the coordinate plane.

Front

What is the effect of a scale factor less than 1 in a dilation?

Back

It reduces the size of the figure.
