How Do You Rotate a Figure 180 Degrees Around the Origin?

We changed the signs of our original x-coordinates from negative to positive
This will give us a reflection in the first quadrant
Changing the signs of the x-coordinates and y-coordinates will reflect of the image in the first quadrant to the fourth quadrant
Each coordinate (x,y) is changed to (-x,-y)
This is our general formula for rotating the figure 180 degrees about the origin

1. Changing the x-coordinates will move the figure into the first quadrant
2. We changed the signs of our original x-coordinates from negative to positive
1. Changing the signs of the x-coordinates and y-coordinates will move the figure into the fourth quadrant
2. We changed the signs of our original y-coordinates from positive to negative
1. Each coordinate (x,y) is changed to (-x,-y)
2. This is our general formula for rotating the figure 180 degrees about the origin
