Back

(6, 12)

Front

What mathematical operation is used with the scale factor in a dilation?

Back

Multiplication

Front

Are two figures that have the same shape but different sizes similar or congruent?

Back

Similar

Front

What is the result of rotating Triangle B 90° counterclockwise around the origin?

Back

Triangle A shows the new location.

Front

What is the scale factor in a dilation?

Back

The ratio of the distance from the center of dilation to a point on the figure before and after the dilation.

Front

What does it mean for two figures to be congruent?

Back

They have the same shape and size.

Front

What is the difference between similar and congruent figures?

Back

Similar figures have the same shape but different sizes; congruent figures have the same shape and size.

Front

If a triangle is dilated by a scale factor of 3, what happens to its area?

Back

The area is multiplied by 3² = 9.

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 determine the new coordinates of a point after a dilation?

Back

Multiply the original coordinates by the scale factor.
