question 4
which theorem or postulate cannot be used to prove triangle congruence?
sss
asa
aas
ssa

Explanation:

• SSS (Side - Side - Side): If three sides of one triangle are equal to three sides of another triangle, the triangles are congruent.
• ASA (Angle - Side - Angle): If two angles and the included side of one triangle are equal to two angles and the included side of another triangle, the triangles are congruent.
• AAS (Angle - Angle - Side): If two angles and a non - included side of one triangle are equal to two angles and the corresponding non - included side of another triangle, the triangles are congruent.
• SSA (Side - Side - Angle): This does not guarantee triangle congruence. For example, when we have two sides and a non - included angle, there can be two different triangles (ambiguous case).

Answer:

SSA.
