Front

What is a reflection in geometry?

Back

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

Front

What is the formula for finding the image of a point (x, y) after reflection over the y-axis?

Back

(-x, y)

Front

What is the definition of symmetry in geometry?

Back

A property where a shape is invariant under certain transformations, such as reflection or rotation.

Front

What is the line of symmetry for a square?

Back

A square has 4 lines of symmetry.

Front

What is the definition of rotation in geometry?

Back

A transformation that turns a figure around a fixed point.
