Angle Relationships & Equations CARD SORT
About This Product
This resource was developed to meet the requirements of the 7th Grade Geometry Standard below:
Use facts about supplementary, complementary, vertical, and adjacent angles in a multi-step problem to write and solve simple equations for an unknown angle in a figure.
This resource contains:
1) Angle Relationships & Equations CARD SORT Activity (printable & version for Google Slides)
--A brief introductory activity that will help students understand the task and promote class discussion.
--Students will cut, sort, and paste 20 different angle relationship images into the following categories:
x°+y°=90° (for complementary angles)
x°+y°=180° (for supplementary angles)
x°+y°=z° (for adjacent angles that have neither a complementary nor supplementary relationship)
x°=y° (for vertical angles)
2) Answer Keys
Note: This activity does NOT require students to solve equations; it is meant to be an activity to help them identify the TYPE of equation that first needs to be set up before attempting to solve the equation.
