Parallel Lines Cut by a Transversal

Activity Overview

Students will develop and strengthen their knowledge about the angles formed when parallel lines are cut by a transversal. The measurement tool helps them discover the relationships between and among the various angles in the figure. Students will draw parallel lines, draw a transversal, and explore angle relationships.

Key Steps

  • Image

    Students explore the angle conjecture by constructing parallel lines and cutting them with a transversal.

  • Image

    Next, students measure all angles.

  • Image

    Then, students observe the changes in angle measurements as they move the transversal.
