Front

What is the definition of translation in geometry?

Back

A transformation that moves every point of a shape the same distance in a given direction.

Front

What is a reflection in geometry?

Back

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

Front

What does a 90° clockwise rotation do to a point (x, y)?

Back

It transforms the point to (y, -x).

Front

What is the effect of a 180° rotation on a point (x, y)?

Back

It transforms the point to (-x, -y).

Front

What is the line of reflection for a reflection across the y-axis?

Back
