Front

What is the definition of reflection in geometry?

Back

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

Front

What is the line of reflection for a point (x, y) reflected over the x-axis?

Back

The line of reflection is the x-axis, and the new point will be (x, -y).

Front

If a point (a, b) is reflected over the y-axis, what is the new coordinate?

Back

(-a, b)

Front

What happens to the coordinates of a point when it is reflected over the line y = x?

Back

The coordinates switch places: (x, y) becomes (y, x).

Front

What is the rule for reflecting a point over the line y = -x?

Back

The new coordinates will be (-y, -x).
