Word Set Square

Challenge

Given a string, e.g. Hello, do the following:

Mirror it:

Hello -> HelloolleH

and create a right triangle using it as the sides:

H         
ee        
l l       
l  l      
o   o     
o    o    
l     l   
l      l  
e       e 
HelloolleH

Which looks sort of like a set square.

That's it!

Scoring

This is code-golf. Shortest answer in each language wins.

The last line should be HelloolleH, not HellolleH

(the same applies to the chars in between as well)

Well spotted, thanks, @Razetime - 'twas easily fixed.
