What is the definition of "similar"?

• A transformation that moves every point of a figure the same distance and the same direction (slide). Shape, size and orientation are preserved

• Two figures that have the same shape and have corresponding proportional side lengths and the image can be obtained from the pre-image by a sequence of transformations

• A transformation that turns a figure around a fixed point

• Two figures that have the same size and shape. Two shapes are this when the image can be obtained from the pre-image by a sequence of transformations.
