6. Angle-Angle-Side

You need to determine that both angles are congruent along with one of the sides:

Corresponding angles are equal as well as one corresponding pair of sides, but this side is not in touch with both angles.

7. Angle-Side-Angle

To determine if this congruence postulate is correct, the corresponding angles must be congruent as well as the side they share:

Corresponding angles are equal and the corresponding sides they share are equal too.

8. Side-Angle-Side

The corresponding sides and the angle between them are equal:

In this case triangle LMN is iscoceles and line MO is a bisector that divides the side LN into two lines of equal lenght LO=ON

Sides LM=MN

And the base angles of an iscoceles triangle are equal so ∠L=∠N

9. Angle-Side-Angle

Same as in item 7, Both angles are their corresponding angles in the other triangle are equal as well as the side they share. In this case:

∠A=∠E

∠B=∠D

AB=DE

10. Side-Angle-Side

Same as in item 8, Two corresponding sides are equal and the angles formed by them.

AC=DF

CB=FE

∠C=∠F
