Recall that square ABCD is similar to square EFGH iff there is a similarity transformation that maps one onto the other.  
A translation maps point A onto point E.  
Then a dilation centered at point E with a scale factor of k=2 maps point B to point F, point C to point G, and point D to point H.  
Angle measures are preserved in all transformations.  A similarity transformations maps square ABCD to square EFGH therefore they are similar.

Triangle KLJ is similar to triangle NPM iff there is a similarity transformation that maps one onto the other.  A translation maps point L onto point P.  A dilation centered at point P with a scale factor of k = v/t maps point K to point N and point J to point M.  Triangle KLJ is mapped to triangle NPM by a similarity transformation therefore they're similar.
