Explanation:

Marked sides are congruent. Shared sides are congruent. Marked angles are congruent. Vertical angles are congruent. The postulates available for proving congruence are ...

  AAS, ASA, SAS, SSS

where the S stands for corresponding congruent sides, and the A stands for corresponding congruent angles.

For right triangles, there is also the HL theorem, where H is the hypotenuse and L is one leg.

__

1) AAS; right angle, vertical angle, marked sides

2) SSS; 2 marked sides, shared side

3) SAS; marked side, vertical angle, marked side

4) HL; hypotenuse and leg are marked

5) not congruent (need at least one side in addition to angles)

6) ASA; marked angle, marked side, vertical angle

7) SSS; 3 marked sides

8) SAS; marked side, marked angle, shared side

9) HL; hypotenuse and shared side

10) not congruent (need at least two angles with one side)

11) ASA; right angle, shared side, marked angle

12) AAS; two marked angles (in the same order), marked side
