Verified Answer :

  1. If it is not raining, then I will not carry an umbrella. 
    2. If two perpendicular lines do not intersect, then they do not form four 90° angles. 
    3. If  <EAD is 80°, then that means <DAB is 100°, because they equal 180°.
    4. A pair of congruent angles are <EAC and <DAB

1. c If it is not raining, then I will not carry an umbrella.

2.a Two intersecting lines are perpendicular if an only if they form four 90 degree angles.

3.a DAB and EAD are supplementary.

4.c FBY; GBX
