4. 30 (vertical angles)
5. 150 (180-30)
6. 65 (angles have to add up to 180)
7. BC (opposite the largest angle)
8. 63 (angles have to add up to 180)
9. De and DF (opposite the largest angles)
10. AC and BC (not sure)
11. altitude (highest point)
12. midpoint (only thing on a line)
13. CG is perpendicular to AB (definition of altitude and process of elimination)
14. cross AB at midpoint (process of elimination)
15. cross BC at midpoint (see above)
