### SSS (side-side-side)

If the 3 sides of a triangle are congruent to the corresponding sides of the other triangle, then the two triangles are congruent.

### SAS (side-angle-side)

If 2 sides of one triangle and the included angle are congruent to the corresponding sides and angle of the other triangle then the two triangles are congruent.

### ASA (angle-side-angle)

If 2 angles and the included side of one triangle are congruent to the corresponding side and angles of the other triangle, then the 2 triangles are congruent.

### HL (hypotenuse-leg)

Two right triangles are congruent if the corresponding hypotenuses are congruent and 1 pair of corresponding legs are congruent.

### ∠'s supp to the same ∠'s are ≅

If two angles are supplementary to the same angle, then they are congruent.

### ∠'s supp to ≅ ∠'s are ≅

If two angles are supplementary to congruent angles, then they are congruent to each other.

### ∠'s comp to the same ∠'s are ≅

If two angles are complementary to same angle, then they are congruent.

### ∠'s comp to ≅ ∠'s are ≅

If two angles are complementary to congruent angles, then they are congruent to each other.
