Instructional Ideas
  • Lead a discussion on why the constructions work and produce congruent figures
  • Have the class brainstorm what other tools can be used to perform constructions, such as string and a pencil can replace a compass
Classroom Considerations
  • Requires the tools for constructions, a straightedge, and compass
Pros
  • Uses colors to show the construction marks
  • Includes a list of extensions
Cons
  • The figures are close together and may not provide enough space for the constructions
