What does it mean for a polygon to be regular?

(Select all that apply)

• The polygon is equilateral,

  all is sides have the same length

• The polygon is equiangular, all angles have the same measure.

• The polygon is normal, just your average guy.

• The polygon is average, the sum of all of it's entries, divided by the total number of entries.

• All elements from set A combined with all elements from set B.

• All elements from set A, set U, and set B.

• Only the elements that A and B have in common.

• None of the elements in sets A or B.

• Only the elements that A and B share, or have in common.

• All of the elements in the whole universal set.

• None of the elements in set A or set B.

• All of the elements from set A combined with the elements from set B.

Which of these means "not A"?

Which of these means "the intersection of set A and set B"?

Which of these means "the union of sets A and B"?
