Access Point #: MAFS.912.G-SRT.2.AP.5aArchived Access Point

Apply the criteria for triangle congruence and/or similarity (angle-side-angle [ASA], side-angle-side [SAS], side-side-side [SSS], angle-angle [AA] to determine if geometric shapes that divide into triangles are or are not congruent and/or can be similar.

Essential Understandings


  • 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 and/or similar.
  • Using graphs or geometry software, mark the pieces of the triangle that are congruent and/ or similar.
  • Given two triangles, determine if the triangles are congruent and /or similar using AA, ASA, SAS, and SSS.
  • Use appropriate tools (e.g., calculator, paper pencil) to solve one-step equations.
  • Use appropriate tools to find the dimensions of a figure.
General Information
Number: MAFS.912.G-SRT.2.AP.5a
Category: Access Points
Date Adopted or Revised: 07/14
Cluster: Prove theorems involving similarity. (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.
