Answer:
They can all be used to prove congruency
Step-by-step explanation:
SAS - which stands for
Side - Angle - Side
This means: Given two triangles with two know sides and one known angle, If the know sides and angle of both triangles are equal, then we cal conclude that the triangles are equal or congruent.
SSA - Stand for
Side - SIde - Angle
This also satisfies the congruency property
ASA - Stands for
Angle - Side - Angle
This also satisfies the congruency property
AAS - Stands for
Angle - Angle - Side
This also satisfies the congruency property
