Coordinates: symmetries Use your mouse to move the red point. (Right-click to clear the traced paths.) Compare the y-coordinates of all the points. Green point y coordinate = Choose... red point x coordinate red point y coordinate negative red point x coordinate negative red point y coordinate Orange point y coordinate = Choose... red point x coordinate red point y coordinate negative red point x coordinate negative red point y coordinate Blue point y coordinate = Choose... red point x coordinate red point y coordinate negative red point x coordinate negative red point y coordinate
