Angle situations (what to look for)­
1. are there vertical angles? the 2 angles are congruent!
2. is there a linear pair? * the 2 angles add to 180 degrees
3. are the angles complementary? * the 2 angles add to 90 degrees
4. are the angles supplementary? * the 2 angles add to 180 degrees

Quiz corrections: DO NOT ERASE!
- a slash through the # means that there is a mistake
- corrections earn you 1/2 points back
- make corrections on a separate sheet of paper
(staple to quiz when complete)
- all work must be shown
- when all 4 group members are done, raise your hand & I'll
grab the quiz
- use this as a study guide:
- if you got less that 80% in a specific section, you
should revise that area before the test
