Hi, don’t really understand why AAA is considered congruent. I thought only 4 permutations fulfilled the congruent triangles principles?
On a related note, for SSS, if the two triangles with sides x, y and z, does it matter where the sides are positioned? for example maybe x is the base of triangle 1 but it becomes height for another triangle. But the two triangles have same x,y and z sides, just different position. Does it mean they are congruent?
