Translations, Reflections, and Rotations

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 translation in geometry?

Back

A translation is a transformation that slides a figure from one position to another without changing its shape or orientation.

Front

What is a rotation in geometry?

Back

A rotation is a transformation that turns a figure around a fixed point at a certain angle.

Front

What is the line of reflection?

Back

The line of reflection is the line over which a figure is reflected to create a mirror image.

Front

How do you identify a translation?

Back

A translation can be identified by the movement of a figure in a straight line, maintaining its shape and size.

Front

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

Back

During a reflection, the coordinates of a point change based on the line of reflection, often resulting in a change in sign for one coordinate.

Front

What is the center of rotation?

Back

The center of rotation is the fixed point around which a figure is rotated.

Front

How do you determine the angle of rotation?

Back

The angle of rotation is determined by the degree measure of the turn from the original position to the new position.

Front

What is the difference between a reflection and a rotation?

Back

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

Front

Can a translation change the size of a figure?

Back

No, a translation does not change the size or shape of a figure; it only changes its position.
