T-Square Grand Trine and Kite Explained?

I want to post my chart to get more details on all three. I have Mars (Taurus 7th) opposing Pluto in Scorpio. Also Pluto conjunct my Asc. Then the Grand Earth Trine with a kite. Not sure how to spot a T-square. But was told there is one present. How do I add chart as well?
