Across
  1. 3. bisector, a segment, line, or plane that intersects a segment at its midpoint
  2. 4. angle, an angle with a degree measure less than 90
  3. 6. for any two points A and B on a line there is another point C between A and B if and only if A, B, and C are collinear and AC+CB=AB
  4. 7. term, words, usually readily understood, that are not formally explained by means of more basic words and concepts
  5. 11. area, the sum of the areas of all faces and side surfaces of a three-dimensional figure
  6. 14. point that lie on the same line
  7. 16. a boundless three-dimensional set of all points
  8. 21. a set of points common to two or more geometric features
  9. 23. angle, two angles that lie in the same plane, have a common vertex and a common side, but no common interior points
  10. 24. angle, two angles with measures that have a sum of 180 degrees
  11. 25. a flat surface made up of points that has no depth and extends indefinitely in all directions
  12. 26. the rays of an angle
  13. 28. a part f a line. It has one endpoint and extends indefinitely in one direction.
  14. 29. is made up of points and has no thickness or width
  15. 32. having the same measures
Down
  1. 1. the common endpoint of an angle
  2. 2. a unit of measure used in measuring singles and arcs
  3. 5. the sum of the lengths of the sides of a polygon
  4. 8. the distance around a circle
  5. 9. the intersection of two non-collinear rays at a common endpoint. The rays are called sides and the common endpoint is called a vertex
  6. 10. the number of square units needed to cover a surface
  7. 12. a measure of the amount of space enclosed by a three-dimensional figure
  8. 13. two non adjacent angles formed by two intersecting lines
  9. 15. points that lie in the same plane
  10. 17. a location
  11. 18. angle, an angle with degree measure greater than 90 and less than 180
  12. 19. in space, the set of all points that are a given point, called the center
  13. 20. angles, two angles with measures that have the sum of 90 degrees
  14. 22. a line that connects two nodes in a network
  15. 27. segment, a measurable part of a line that consists of two points, called endpoints, and all of the points between them
  16. 30. angle, an angle with a degree measure of 90
  17. 31. the two parallel congruent faces of a polyhedron
