1. trace over bga.
2. look to find a supplementary angle to bga. (to
create 90 or 180 degrees? )
3. trace over that angle that makes the two angles
together supplementary
4. write the name of the here (should be 3 letters
written in the right order). 2
5. if _bga is 50° what is the measure of the
supplementary angle listed in #4
6. show how you got that measure by writing a math
problem here.
