The document provides instructions for students to learn about different types of angles and their relationships. It includes directions to sort pictures of angles into categories, complete a concept map on one angle type, measure angles using a protractor, draw angles given measurements, watch videos on measuring acute angles, define and draw adjacent and vertical angles, classify angles as complementary or supplementary using an online tool, work examples, and do homework problems classifying and relating different angles.

1. 10.1 Angles 10.3 Angle Relationships 1—Measure angles 2—Identify and apply angle relationships

2. Sort Sort the pictures into 4 categories and name each type of angle.

3. Angles

4. Concept Map Pick one type of angle and complete a concept map for it. Give the definition, draw a picture, and tell where you would find it in the real world.

5. Measuring and constructing angles What do you use to measure a line? What do you use to measure an angle?

6. Video Measuring acute angles video (time 1:10) Measure the 4 angles on your paper.

7. Drawing angles---Draw . Draw a ray with a measure of 75 °. Place the center point of a protractor on A. Align the ray with 0°. Use the scale that begins with 0°. Locate the mark labeled 75. Then draw the other side of the angle.

8. 10-3 Angle Relationships Video Handout page 8 Write a definition for adjacent and vertical angles. Then draw a picture of both.

9. Complementary Angles

10. Supplementary Angles

11. Classify as complementary or supplementary http://www.321know.com/geo-comp-or-sup.htm
