Not enough information is provided

If it is rotated  $90\degree$ clockwise it will no longer measure  $90\degree$  

If it is reflected over  $y=x$ it will still measure  $90\degree$  

If it is translated 5 units up it will no longer measure  $90\degree$  

If it is translated 2 units right, it will still measure  $90\degree$  

If it is reflected over the y-axis it will still measure  $90\degree$
