How do we graph rotations ?
Graphing rotations is basically taking a shape and turning it depending on what degree measure you're given.
Rotation: figure is turned around a single point.
90 degrees
(A,B)---->(-B,A)
(5,2)----->(-2,5)

(A,B)---->(-B,A)
(5,2)----->(-2,5)
180 degrees
(A,B)---->(-A,-B)
(5,2)---->(-5,-2)
270 degrees
(A,B)---->(B,-A)

How do we identify transformations ?
Transformation is moving a geometric figure on a graph.
Four types of Transformations:
1.Translation: Every point is moved the same distance.
2.Rotation: Figure is turned around a single point.
3.Reflection: Figure is flipped over a line.
4.Dilation: Changing the size of an image.
