Front

How do you perform a dilation on a figure?

Back

To perform a dilation, multiply the coordinates of each point by the scale factor.

Front

What is the scale factor in dilation?

Back

The scale factor is the ratio of the size of the image to the size of the original figure.

Front

What is the result of reflecting a point (x, y) over the x-axis?

Back

The result of reflecting a point (x, y) over the x-axis is (x, -y).

Front

What is the result of rotating a point (x, y) 90 degrees counterclockwise around the origin?

Back

The result of rotating a point (x, y) 90 degrees counterclockwise around the origin is (-y, x).
