State the criteria for proving two triangles congruent using AAS congruence.

• Two triangles are congruent using AAS congruence if two angles and the non-included side of one triangle are congruent to two angles and the non-included side of another triangle.

• Two triangles are congruent using AAS congruence if the hypotenuse and one leg of one triangle are congruent to the hypotenuse and one leg of another triangle.

• Two triangles are congruent using AAS congruence if all three sides of one triangle are congruent to all three sides of another triangle.

• Two triangles are congruent using AAS congruence if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle.
