This micro-credential covers the congruence strand of high school geometry as expressed in the New York State Next Generation Mathematics Learning Standards (GEO-G.CO.1 through GEO-G.CO.7). It is the natural first badge in the Geometry domain and a prerequisite for credentials covering the triangle congruence criteria and proof, which are not yet written.

What it certifies

  1. Define the basic objects of plane geometry foundation
  2. Represent transformations in the plane foundation
  3. Describe and draw rotations, reflections, and translations intermediate
  4. Use rigid motions to decide and prove congruence advanced

How it is earned

performance-task

Rigid Motion Congruence Task

A performance task in which the learner decides whether pairs of figures are congruent and proves it with rigid motions.

Who can issue it

  • Assess with the adopted version of the Rigid Motion Congruence Task, scored Proficient by a reviewer who did not teach the learner.
  • Retain the learner's evidence for verification, with the learner's consent, and give the learner a copy.
  • Issue as an Open Badges 3.0 credential referencing this credential's id and version.
