1-90° clockwise rotation(x,y) → (y,-x)
clockwise = -x
290° counterclockwise rotation(x,y) → (-y,x)
counterclockwise = -y
3180° clockwise or counterclockwise(x,y) → (-x,-y)
switch the signs, make negative
4270° counterclockwise(x,y) → (y,-x)
270° = -90°
5-270° clockwise(x,y) → (-y,x)
-270° = 90°
6x-axis reflection(a,b) → (a,-b)
7y-axis reflection(a, b) → (-a, b)
8origin reflection(a, b) → (-a, -b)
9line y = x reflection(a, b) → (b, a)
10line y = -x reflection(a, b) → (-b, -a)
11line x = a(x, y) → (2a - x, y)
