Access Point #: MAFS.912.G-SRT.1.AP.2aArchived Access Point

Determine if two figures are similar.

Essential Understandings


  • Select two objects that are the same shape.
  • Use appropriate tools as needed to duplicate a shape (e.g., wiki sticks, computers, interactive white boards, markers).
  • Use geometry software to create dilations.
  • Identify congruent angles of similar figures.
  • Describe the characteristics of the two figures that are similar.
  • Use geometry software to construct and compare figures based on angle measurements and side lengths.
  • Use proportions to compare figures based on side lengths to determine similarity.
  • Understand the following vocabulary: similar, congruent, angles, corresponding, transformation.
General Information
Number: MAFS.912.G-SRT.1.AP.2a
Category: Access Points
Date Adopted or Revised: 06/14
Cluster: Understand similarity in terms of similarity transformations. (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.
