Geometry Reflection Rotations Translation

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 rotation in geometry?

Back

A rotation is a transformation that turns a figure around a fixed point, known as the center of rotation.

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 does it mean for shapes to be congruent?

Back

Congruent shapes are identical in shape and size, meaning they can be superimposed on each other.

Front

What is the axis of reflection?

Back

The axis of reflection is the line over which a figure is flipped during a reflection.

Front

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

Back

The coordinates of a point change by adding or subtracting the same values to/from the x and y coordinates.

Front

What is the center of rotation?

Back

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

Front

How do you determine the angle of rotation?

Back

The angle of rotation is the measure of the turn from the original position to the new position of the figure.

Front

What is the difference between a rotation and a reflection?

Back

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

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.
