By: Cynthia Gandarilla

A function from a plane to itself that is a one-to-one correspondence.

4. Translation
A transformation of a plane that moves every point of a plane a specified distance in a specified direction along a straight line.

7. Reflection
A reflection in line is a transformation from the plane to the plane that pairs each point with P

10. Rotation
A transformation of the plane determined by holding one point, the turn center, fixed and rotating the plane about this point by a certain amount and a certain direction.
