Front

Define translation in geometry.

Back

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

Front

Define reflection in geometry.

Back

Reflection is a transformation that flips a shape over a line, creating a mirror image.

Define rotation in geometry.

Back

Rotation is a transformation that turns a shape around a fixed point at a certain angle.

What is the effect of a translation on a shape?

Back

A translation shifts the shape without changing its size, shape, or orientation.

What happens to a shape during a reflection?

Back

During a reflection, the shape is flipped over a line, resulting in a mirror image.

What is the center of rotation?

Back

The center of rotation is the fixed point around which a shape is turned during a rotation.

How do you identify a rotation transformation?

Back

A rotation can be identified by the angle of rotation and the direction (clockwise or counterclockwise) around a center point.

What is the difference between a reflection and a rotation?

Back

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