Across
  1. 1. a type of symmetry in which a figure looks exactly the same after rotating it some angle less than 360
  2. 4. every polygon has a exterior angle sum of 90 degrees
  3. 6. to calculate the measure of one interior angle of a regular polygon
  4. 11. the sum of the measure is 360 degrees
  5. 13. the specific point around the shape is rotated to achieve rotational symmetry
  6. 14. a quadrilateral with four right angles
  7. 15. two parallel sides
  8. 17. a quadrilateral with four congruent sides that are equal in length
  9. 18. two shapes or figures that are the same exact size and shape
  10. 20. a polygon having n sides and n verticals
Down
  1. 2. a quadrilateral with only one pair of parallel sides and non congruent base angles
  2. 3. a quadrilateral with two sets of parallel lines
  3. 5. an imaginary line that divides a shape into two identical halves
  4. 7. a polygon where all the sides are equal in length
  5. 8. trapezoid a quadrilateral with one set of parallel lines with congruent base angles
  6. 9. a quadrilateral with two pairs of congruent sides
  7. 10. when an object appears the same after being rotated by 360/n degrees
  8. 12. polygon that has all equal sides and angles
  9. 16. a quadrilateral with four equal sides and four right angles
  10. 19. a polygon where all the angles are equal in length
