Instructional Ideas

  • Have class members write down the corresponding sides and angles based upon their measures
  • Find out if a single transformation can show the two triangles are congruent
Classroom Considerations

  • The class should be familiar with the properties of transformations
Pros

  • Describes common misconceptions
  • Provides questions for the teacher to gain further understanding of pupils' thinking
Cons

  • The labeling of the triangle is not correct based on the given congruence statement
  • Answer key uses triangles placed on a grid
