This video shows how to work step-by-step through one or more of the examples in Supplementary Angles.
This video gives more detail about the mathematical principles presented in Supplementary Angles.
Ten problem quiz, short answers. Students need to identify supplementary angles and give justification proving that the angles are supplementary. Students need to solve for missing supplementary angles, both with simple arithmetic and algebraically.
A list of student-submitted discussion questions for Supplementary Angles.
What if you were stranded at sea? Or on a desert island? How would you use angles to determine your position?
This study guide reviews angle nomenclature, how to measure angles, different types of angles, congruent angles, and angle pairs.
