Solve real-life and mathematical problems involving angle measure, area, surface area, and volume.

Students will 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.

Tutorial

1. Title your notes FINDING THE MISSING ANGLES.

2. Write the objective on the first line of your notes.

3. Split the rest of your notebook into three sections and label them: Vertical Angles, Complementary Angles, Supplementary Angles.

4. Write everything you learn about these angles under the corresponding title.

5. You must have at least the definition, picture and example for each angle.

6. After you take notes, take the quiz and see how well you do on it. LABEL THIS SECTION: QUIZ on your notes and don't forget to show your work on there as well. If you get three correct, then you are done, if you don't review your notes again and try the quiz again.

7. Finally, answer the big question at the bottom.

Have fun!

Complementary angles are two angles with a sum of 90º.

Supplementary angles are two angles with a sum of 180º.

Vertical angles are two angles whose sides form two pairs of opposite rays. We can think of these as opposite angles formed by an X.

*and remember, adjacent angles are angles that are NEXT to each other and share an angle*

This video will help you get an idea of what complementary, supplementary, adjacent and vertical angles are.

Please take notes on each angle and also follow along with the last three problems. Write the last three questions on your notebook as well.

Don't forget that you may pause, replay or restart the video at any time.
