Across
  1. 6. A polygon in which all sides are the same length and all angles have the same measure
  2. 8. A polygon with four sides and four angles
  3. 9. A 2-dimensional figure formed by three or more line segments (sides) that meet only at their endpoints (vertices) to make a closed path
  4. 11. A quadrilateral with at least one pair of parallel sides
  5. 13. A triangle with a right angle (90°)
  6. 14. An angle with a measure of 90°
  7. 15. A triangle with three acute angles
  8. 20. Lines that never meet or intersect
  9. 21. A quadrilateral with two pairs of parallel sides; opposite sides have the same length and opposite angles have the same measure
  10. 22. An angle with a measure more than 90°, but less than 180°
  11. 23. Part of a line connecting two points, it has definite end points
  12. 24. The figure formed by two rays, called the sides of the angle, sharing a common endpoint (the vertex of the angle)
  13. 27. A triangle with all three sides equal in length, each angle of an equilateral triangle measures 60°

Down
  1. 1. A triangle with one obtuse angle
  2. 2. Two angles that are next to each other, they have a common vertex and one common side
