# Reflect Across the Origin

You can reflect figures across the origin (0, 0).

For example, to reflect point *A* across the origin, draw a line from point *A* through the origin and mark a point on the other side of the origin that is the same distance from the origin.

- Reflect the given figure across the origin. Label the coordinates of vertices of the original triangle and the reflected triangle.
- Reflect other figures across the origin.
- What rule can you use to reflect any point (
