In ∆ABC and ∆LMN
Angle A is congruent to Angle L
Angle B is congruent to Angle M
Angle C is congruent to Angle N
It is not necessary that ∆ABC and ∆LMN are congruent.
Even after having
Angle A is congruent to Angle L
Angle B is congruent to Angle M
Angle C is congruent to Angle N
Sides of triangles can be of different size.
