We can apply the SAS postulate to conclude that the two triangles are congruent.
In geometry, congruence between two triangles means that the two triangles are identical in shape and size. Several postulates and theorems can be used to establish the congruence of triangles.
ASA (Angle-Side-Angle): This postulate states that if two angles and the included side of one triangle are congruent to the corresponding angles and included side of another triangle, then the triangles are congruent.
SSS (Side-Side-Side): This postulate states that if the three sides of one triangle are congruent to the three sides of another triangle, then the triangles are congruent.
AAS (Angle-Angle-Side): This postulate states that if two angles and a non-included side of one triangle are congruent to the corresponding angles and side of another triangle, then the triangles are congruent.
SAS (Side-Angle-Side): This postulate states that if two sides and the included angle of one triangle are congruent to the corresponding sides and included angle of another triangle, then the triangles are congruent.
Among the given options, SAS (option D) is the postulate that proves the congruence of two triangles.
