Transformations Review

Front

What is a dilation in transformations?

Back

A dilation is either an enlargement or a reduction of a figure.

Front

In a translation, if an image is moved left 5 units, what is the transformation?

Back

The image is translated left by 5 units.

Front

What axis is the image reflected in if it is reflected in the y-axis?

Back

The image is reflected in the y-axis.

Front

What is the image of the point (-3,-4) when rotated 180 degrees around the origin?

Back

The image of the point is (3,4).

Front

What is the image of the point (7,8) when rotated 90 degrees counterclockwise around the origin?

Back

The image of the point is (-8,7).

Front

Define translation in geometry.

Back

Translation is a transformation that moves every point of a figure the same distance in the same direction.

Front

What is the effect of a reflection in the x-axis on a point (x,y)?

Back

The image of the point will be (x,-y).

Front

What happens to a figure during a rotation of 90 degrees clockwise around the origin?

Back

The image of the point (x,y) will be (y,-x).

Front

What is the difference between a rotation and a reflection?

Back

A rotation turns a figure around a point, while a reflection flips a figure over a line.

Front

What is the result of a dilation with a scale factor greater than 1?

Back

The figure is enlarged.
