Reflections on the Coordinate Plane

Front

What is a reflection in geometry?

Back

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

Front

What are the coordinates of a point reflected over the x-axis?

Back

If a point is (x, y), its reflection over the x-axis is (x, -y).

Front

What are the coordinates of a point reflected over the y-axis?

Back

If a point is (x, y), its reflection over the y-axis is (-x, y).

Front

What are the coordinates of a point reflected over both the x-axis and y-axis?

Back

If a point is (x, y), its reflection over both axes is (-x, -y).

Front

Reflect the point (-3, 1) across the x-axis. What are the new coordinates?

Back

(-3, -1)
