How hard can it be to split something in half? Learners investigate how previously learned concepts from angle bisectors can be used to develop ways to construct perpendicular bisectors. The resource also covers constructing a perpendicular from a point not on a line, as well as constructing parallel lines.

Instructional Ideas
- Have class members work in pairs throughout the lesson
Classroom Considerations
- There are several different constructions to be learned in this lesson, so depending on student needs, the lesson could be split into two days
- The lesson assumes that Lesson Three of the module has been completed and builds on previously learned information
- The fourth installment of a 36-part series
Pros
- Worksheet includes all relevant vocabulary definitions and cloze notes
- The teacher version includes a copy of the student version with answers filled in
Cons
- The "Mathematical Modeling Exercise" section is labeled in different places of the lesson in the teacher guide and student worksheets, which could potentially be a source of confusion
