Sorry, I saw the title and recognized "Angle theorem" so I'm going to take a stab at what I remember:

Angle-Side-Angle Theorem ---> if two angles, and the side between them are equal in two seperate triangles, then the triangles are congruent....

Side angle Side ---> If two sides, and the angle included between them are equal on any two triangles, the nthe triangles are congruent

Side Side side theorem ---> If 3 sides are equal on any two triangles, the triangles are congruent

Angle angle Angle theorem ---> If three angles are the same on any two triangles, the triangles are SIMILAR, but not necessarily congruent... they are proportional.

I'm just a newbie, wishing to be an engineer... Still in grade 12... So make fun of my answer all you want :P I might be thinking of the wrong thing.
