Why don't we have SSA???

If a pair of congruent triangle that is SAS (Side-Angle-Side), but the angle's degree is 90, I should write SAS or RHS???

RE: Why don't we have SSA???
因為 SSA的話, 個三角形的樣有兩個可能性,
睇下張圖: http://2uploadhk.com/view/19667/SSA2.JPG
佢地有一個相同大小的角( GREEN),
有一條相同長度的線(PINK).
再有多一條相同長度的線(BLUE & ORANGE),
但佢地唔係相等的

如果其中一隻角係90度
而兩個三角形的斜邊是一樣的話...
RHS
