  1. 4. a 5 sided polygon
  2. 6. a polygon that has 4 sides. The sun of the angles is 360 degrees. All angles do not have to be right
  3. 7. an angle that measures between 90 and 180 degrees
  4. 8. an angle that measures less than 90 degrees
  5. 10. a triangle whose sides all have different lengths; no sides are congruent
  6. 14. a triangle that has at least two sides of the same length
  7. 15. only one pair of parallel lines
  8. 16. a polygon whose sides all have the same length and whose angles are the same length
  9. 17. a triangle with one angle that is 90 degrees; the properties of this is that it is a polygon, had 3 sides and one 90 degree angle
