Rotation: the action of rotating around an axis or center.
Counter clockwise: in the opposite direction to the way in which the hands of a clock move around. <---
Clockwise: in the same direction as the way in which the hands of a clock move around. -->
Transformation: a thorough or dramatic change in form or appearance
The rules for rotation:
90° clockwise rotation: (x,y) becomes (y,-x)
90° counterclockwise rotation: (x,y) becomes (y,x)
180° clockwise and counterclockwise rotation: (x, y) becomes (-x,-y)
270° clockwise rotation: (x,y) becomes (-y,x)
270° counterclockwise rotation: (x,y) becomes (y,-x)

Answer:
Rotation:the action of rotating(moving around) about an axis(fixed point) or a centre
Counter clockwise: moving in the opposite direction to which the hands of a clock move
Clockwise: moving in the same direction as the hands of a clock move
Transformation: the complete change of one form to another
Rotation rules:
90° clockwise rotation: (x,y) becomes (y,-x)
90° counterclockwise rotation: (x,y) becomes (y,x)
180° clockwise and counterclockwise rotation: (x, y) becomes (-x,-y)
270° clockwise rotation: (x,y) becomes (-y,x)
270° counterclockwise rotation: (x,y) becomes (y,-x)
