Interactive multiple-choice quiz: Proving Triangles Congruent

Triangle congruence is a fundamental concept in geometry, allowing us to determine if two triangles are identical in shape and size based on limited information. The primary postulates include SSS (Side-Side-Side), where all three pairs of sides are equal; SAS (Side-Angle-Side), requiring two sides and the angle between them; ASA (Angle-Side-Angle), involving two angles and the side between them; and AAS (Angle-Angle-Side), where two angles and a non-included side are congruent. These criteria are essential for proofs and solving complex geometric problems without needing to measure every dimension.
