Vertical Angles and Linear Pairs
This applet demonstrates Vertical Angles and Linear Pair relationships.
Use the above applet to answer the following questions. You must answer these questions on a separate sheet of binder paper that will be stamped when you complete the investigation.
- Check each of the boxes labeled 1 and 2 under Vertical Angles. Where are vertical angles located? What do you observe about the angle measures of these vertical angles?
- Check each of the boxes labeled 3, 4, 5, and 6 under Linear Pairs. What do you observe about the measures of each pair of angles that form a linear pair?
- Click and drag the blue points to change the angle measures. Do the angle relationships change?
- Complete the following conjectures: If two angles are vertical angles, then ____________________. If two angles form a linear pair, then _____________________.
