Vertical and Adjacent Angles

Activity Overview

In this introductory or review activity, students will explore vertical and adjacent angles. They will define and identify pairs of angles. Then they will change the intersecting lines of a geometric model to make conjectures about the relationships of the pairs of angles.

Key Steps

  • Image

    In Problem 1, students begin their exploration of vertical angles. Students will move points on the intersecting lines to discover the properties of vertical angles and make a conjecture.

  • Image

    In Problem 2, students will investigate adjacent angles constructed from two intersecting lines and make a conjecture.
