A transformation is is when you move a geometric figure.
There are four types of transformations:
+Translation
+Rotation
+Dilation
+Reflection
Example of a translation:

 Example of a rotation:

Example of a reflection:

Example of a dilation:

T(5,2) You would add five to x. Then add 2 to y.
A problem would look similar to A is (0,0) B (2,2) C (0,2) and D is (2,0). What would be the coordinates if R90 degrees.
