Cartesian Plane Flashcards
When something rotates 90 degrees anticlockwise around the origin, what happens to the coordinates?
x and y values swap over and the original y value changes (positive to negative or vice versa)
When something rotates 180 degrees around the origin, what happens to the coordinates?
The sign for the x and y values change
When something rotates 270 degrees anticlockwise around the origin, what happens to the coordinates?
The x and y values swap and the original x value changes sign (from positive to negative and vice versa).
When something rotates around the origin 90 degrees clockwise, what happens to the coordinates?
Apply the rule for 270 degrees anticlockwise
When something rotates 270 degrees clockwise around the origin, what happens to the coordinates?
Apply the same rule for 90 degrees anticlockwise.
When writing coordinates, how do you write it?
(x,y)
