Transformation translation

I know when a figure is a transformations or a plane shape is by if a shape has a prime on the right side of a letter.for example r' and e' just like that. A change in spot size or a shape.When a shape is transformed , it will have a NEW coordinate points. The points will be called with an apostrophe ( or prime ).Translation is a point that is a shape that move the distance and in the same angle.No because the original shape always have to be the same. For ex if it is a triangle the next figure have to be a shape.By finding out were is located and then add or subtract the units is were it is located!!!!!!!!!!!!!!
