Transformations and Congruence · Geometry & Measurement

Triangle Congruence Criteria

Establishing the minimum requirements for proving two triangles are identical.

Key Questions

  1. 1Why is Side-Side-Angle not a sufficient condition for congruence?
  2. 2How does the concept of rigidity in triangles apply to structural engineering?
  3. 3Can we prove congruence using only information about angles?
