Instructional Ideas

  • Have pupils create flashcards to keep track of all of the vocabulary terms
Classroom Considerations

  • String is required if completing the opening exercise
  • Assumes pupils know how to construct angle bisectors and perpendicular bisectors from the previous lessons
  • The fifth installment of a 36-part series

  • Cloze notes reduce writing load 
  • Connects and summarizes previously learned material

  • Problem set does not touch upon points of concurrencies
