Translations, Rotations, Reflections, and Dilations.

Front

What is a translation in geometry?

Back

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

Front

What is a rotation in geometry?

Back

A rotation is a transformation that turns a figure around a fixed point called the center of rotation.

Front

What is a reflection in geometry?

Back

A reflection is a transformation that flips a figure over a line, creating a mirror image.

Front

What is a dilation in geometry?

Back

A dilation is a transformation that changes the size of a figure but not its shape, using a scale factor.

Front

What does the scale factor in a dilation represent?

Back

The scale factor indicates how much larger or smaller the image will be compared to the original figure.

Front

How do you identify a rotation?

Back

A rotation can be identified by the angle of rotation and the center of rotation.

Front

What is the difference between a translation and a reflection?

Back

A translation moves a figure without changing its orientation, while a reflection flips it over a line.

Front

What is the effect of a scale factor of 2 in a dilation?

Back

A scale factor of 2 means the image will be twice as large as the original figure.

Front

How can you determine if a transformation is a reflection?

Back

If the figure appears as a mirror image across a line, it is a reflection.

Front

What happens to the coordinates of a point during a translation?

Back

The coordinates of a point are changed by adding the translation vector to them.
