A key component of this postulate (that is easy to get mistaken) is that the angle. must be formed by the two pairs of congruent, corresponding sides of the triangles.In EFG, the legs are segments EG and EF. The third side is called the base. In EFG, the base is segment GF. The angles on either side of the base are called base angles. In EFG, the base angles are <G and <F. The angle opposite the base is called the vertex angle. In EFG, the vertex angle is <E.
