Definition & Meaning of Triangle Congruence
Triangle congruence refers to the condition where two triangles are identical in shape and size, meaning that their corresponding sides and angles are equal. This concept is fundamental in geometry, as it allows mathematicians and students to establish relationships between different triangles. There are specific criteria, known as postulates and theorems, that help determine when triangles are congruent.
Understanding triangle congruence is essential for solving various geometric problems. For instance, if two triangles are proven congruent, one can infer properties about the triangles without measuring each side or angle directly. This can simplify calculations in both theoretical and practical applications.
