Answer 1

1.EB is parallel to FC because they are on opposite sides and will never touch

2.scalene triangle

right angle

isosceles

3. supplementary angles add to 180 degrees

180-62=118

complementary angles add up to 90

90-62=28

4. 180 - 68 - 38 = 74

5. 6 sides=hexagon

8. sides= octagon

9. sides = nonagon

10. supplementary angles add to 180 degrees

so angle EOC is supplementary to EOF
