Overview of Unit
Day 1: Students will begin by defining parallel lines and transversals. The
students will then use Geometer’s Sketchpad to construct two parallel lines
and a transversal that cuts through them (this should be done with the
teacher’s assistance). They will then be asked to find the interior angles,
and to discover the properties of the interior angles. This will lead to the
students defining alternate interior angles and same side interior angles.
Day 2: On their own, students will repeat the procedure for Day 1
(Students will construct two parallel lines cut by a transversal), and will then
determine where the exterior angles are located. Next, students will define
exterior angles and alternate exterior angles. Students should save a copy
of their work for the Day 3 activities.
Day 3: Students will retrieve their saved copy of their work from Day 2.
Today, students will explore the properties of vertical angles and
corresponding angles, and define both.
Day 4: Students will demonstrate their understanding of the angles formed
by parallel lines. They will complete two activities to test their knowledge.
Day 5: Students will demonstrate an understanding of the material covered
in this chapter. They will work on a crossword puzzle that tests their
knowledge of the definitions. Then they will work on a “chapter test” from
the Informal Geometry textbook to test their ability to apply the concepts
learned throughout the week.
