Name: _________________________________________
Date: ________ Period: _______
Look at the special angles website on 8th grade Mathematics website. Read under the headings: Fill in the
missing notes from the website. Once notes are copied, complete the problems on back of worksheet.
1. Read “Parallel Lines” and “Pairs of Angles.”
2. Click on the various items under “Choose One.”
3. Using the diagram at the right with the information
from the website:
 Label the parallel lines with “A” and “B”
 Label the transveral line with “T”
------------------------------------------------------------------------Name the examples of each based on the diagram at right:
- Vertical angles: _____ and ______
- Corresponding angles: _____ and _____
- Alternate Interior Angles: _____ and _____
- Alternate Exterior Angles: _____ and _____
--------------------------------------------------------------------------------------------------------------------------------------------Read the following statements and check off the box.
 All of these special angles are equal to one another. They are the same degrees. In this arrangement, all of
the acute angles are the same degrees and all of the obtuse angles are the same degrees.
