Resource:

Finding vertical and supplementary angles (Group Activities)

NOTES:
1. This activity incorporates specific student roles for group work.
2. There are two different sets of materials so that the same activity structure can be done twice.
Activity Objectives:
- To help students learn how to work together effectively.
- To help students see connections between vertical and supplementary angles in geometry.
- To help students see connections between algebra and geometry.

Prove geometric theorems. Prove theorems about lines and angles. Theorems include: vertical angles are congruent; when a transversal crosses parallel lines, alternate interior angles are congruent and corresponding angles are congruent; points on a perpendicular bisector of a line segment are exactly those equidistant from the segment’s endpoints.

Common Core: Supporting Standards:

G-CO.D.12

Make geometric constructions. Make formal geometric constructions with a variety of tools and methods (compass and straightedge, string, reflective devices, paper folding, dynamic geometric software, etc.). Copying a segment; copying an angle; bisecting a segment; bisecting an angle; constructing perpendicular lines, including the perpendicular bisector of a line segment; and constructing a line parallel to a given line through a point not on the line. Clarification: Constructions include but are not limited to the listed constructions. Example: constructing the median of a triangle or constructing an isosceles triangle with given lengths.
