FLASHCARD - Name the Transformation

Front

What is a transformation in geometry?

Back

A transformation in geometry refers to the movement of a figure in a plane. This can include operations such as translation, rotation, and reflection.

Front

Define translation in geometry.

Back

Translation is a type of transformation that slides a figure from one position to another without turning it. The shape and size remain the same.

Front

What is reflection in geometry?

Back

Reflection is a transformation that flips a figure over a line, creating a mirror image of the original figure.

Front

Explain rotation in geometry.

Back

Rotation is a transformation that turns a figure around a fixed point, known as the center of rotation, by a certain angle.

Front

What is the difference between rotation and reflection?

Back

Rotation turns a figure around a point, while reflection flips it over a line, creating a mirror image.

Front

What is the center of rotation?

Back

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

Front

How do you identify a translation?

Back

A translation can be identified by observing that all points of the figure move the same distance in the same direction.

Front

What happens to the size and shape of a figure during a reflection?

Back

During a reflection, the size and shape of the figure remain unchanged; only its position and orientation change.

Front

Can a transformation change the size of a figure?

Back

No, transformations like translation, rotation, and reflection do not change the size of a figure; they only change its position or orientation.

Front

What is a line of reflection?

Back

A line of reflection is the line over which a figure is flipped to create a mirror image.
