Answer 12

Basically when you describe two angles as being complementary, you are saying that the angles add up to form 90 degrees. Therefore you have to start off with a case scenario where you have a 90 degree angle (in this case there was a line DEC drawn with a perpendicular line EG drawn from it that was used to show the proof that angles GEF and FEC are complementary)

To remember what complementary and supplementary stand for, remember
Complementary starts with "co" -> the angles add up to form a COrner (90 degrees)
Supplementary starts with "s" -> the angles add up to form a Straight line (180 degrees)

Answer 13

1. Given
2. Definition of Right Angle
3. If the exterior sides of 2 adjacent angles form a straight angle, then the two angles are called a linear pair. (You probably can get by with just "Def of Linear Pair.")
4.Linear pairs of angles are supplementary.
5. Substitution
6. Subtraction
7. Angle Addition Postulate
8. Substitution (could use Transitive Property)
9. Definition of Complementary Angles.
