Use the definition of congruence, based on rigid motion, to develop and explain the triangle congruence criteria; ASA, SSS, and SAS.
Clarifications:

Essential Understandings

Concrete:

  • Given two triangles, match the corresponding sides on each triangle.
  • Given two triangles, match the corresponding angles on each triangle.
  • Mark the pieces of the triangle that are congruent.
  • Identify which triangles are and are not congruent.
Representation:
  • Using graphs or geometry software, mark the pieces of the triangle that are congruent.
General Information
Number: MAFS.912.G-CO.2.AP.8a
Category: Access Points
Date Adopted or Revised: 07/14
Cluster: Understand congruence in terms of rigid motions. (Geometry - Major Cluster) : 

Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.
