Also known as [b]AA Postulate[/b].

I'll just try:
>> angles Q and R are right angles. --> [i]Given.[/i]
...
>> angle RST and angle QSP are vertical angles. --> [i]Two angles are vertical angles if the sides of one angle are the opposite rays of the sides of the other angle.[/i]
>> angle RST is congruent to angle QSP. --> [i]Vertical angles are congruent.[/i]
>> triangles RST and QSP are congruent --> [i]AA Postulate[/i]
<-- See this face?? It's having a hemorrhagic effect (trying so hard solving geometric problems).
