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

What is a rotation?

Back

A rotation is a transformation that turns a shape around a fixed point, called the center of rotation, by a certain angle.

Front

Define reflection in geometry.

Back

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

Front

What is the effect of a 90-degree rotation counterclockwise about the origin?

Back

A 90-degree rotation counterclockwise about the origin transforms the coordinates (x, y) to (-y, x).

How does reflecting a shape over the x-axis affect its coordinates?

Back

Reflecting a shape over the x-axis changes the coordinates (x, y) to (x, -y).

How do you describe a sequence of transformations?

Back

To describe a sequence of transformations, list each transformation in the order they are applied, specifying the type and direction.
