Congruent triangle

The key of triangle congruence is to grasp whether the corresponding equivalence is an edge or an angle.

SAS is obviously talking about edges and corners, so it must be that both sides are equal to the included angle and the triangle is congruent.

It should be noted that the angle mentioned here must be the included angle between sides, and other angles are not.

The angle side of AAS angle means that two angles and one side are equal and a triangle is congruent.

Remember that SAS has two sides and AAS has two corners.
