Module 5: Angles

 

Lesson Summary

 

The game being played in the photograph involves first folding a square sheet of paper into a shape that can be closed or opened as a name is spelled or a number is counted out. The process of folding a piece of paper into various shapes is a traditional Japanese folk art called origami. The folds create an interplay of angles and geometric shapes. Can you identify congruent angles in the figure?

 

In this lesson you explored the following questions:

• How are congruent angles defined?
• How are congruent angles constructed?

Check your level of understanding of the materials covered in this lesson by completing “Lesson 2 Traffic Lights.” If you select an amber or red traffic light in the multimedia piece, you will receive information about additional work you can complete to improve your understanding of the topics. Complete the suggested work before you proceed to the Lesson 2 Assignment. If you experience difficulty, contact your teacher before starting the Lesson 2 Assignment.

Resave your Assignment Booklet in your course folder and submit a copy to your teacher for assessment.

 

Unit 3 Project

 

Now, before you move on to Lesson 3, take a good look at the topic you chose for your Unit Project. The Unit 3 Project deals with angles.

• Where can you see angles?
  
• Are angles part of the board game or field lines?
  
• Are angles involved in the ball motion or player movements? Are angles visible in the design or in its construction?
  
• Are any of these angles congruent?

List areas where angles could possibly be found, and include sketches and photos where possible. Remember to save all this work, since it will be needed to complete your Unit 3 Project.
