Side Angle Theorems

Side-Angle-Angle (SAA/AAS)

if 2 angles and a non-included side of a Δ is ≈ to 2 angles and non-included side of other Δ, then the Δs are ≈

Angle-Side-Angle (ASA)

if 2 angles of an included side of a Δ is ≈ to 2 angles of an included side of other Δ, then the Δs are ≈

Side-Angle-Side (SAS)

if 2 sides of an included angle of a Δ is ≈ to 2 sides of an included angle of other, then the Δ are ≈

Corresponding parts of a congruent triangles are congruent (CPCTC)

if 2 Δ are ≈, the corresponding parts are ≈

Side-Side-Side (SSS)

if 3 sides of a Δ is ≈ to 3 sides of other Δ, then the Δs are congruent
