Answer: Hello mate!
two angles can mett the AAA criteria, which says that they have the same angles, but not be congruent, because two angles of different sizes can have the same angles.
For example the triangle rectangle with hypotenuse = √2 and both cathetus = 1 (the angles are 90°, 45°, 45°)
and the triangle rectangle with hypotenuse √8 and both cathetus = 2.
(the angles are 90°, 45°, 45°)
this triangles have a different length in all the sides but have the same angles, then they succed the AAA criteria, but are not congruent triangles.
