Across
  1. 2. Lines in three dimensional space that do not intersect and are not parallel.
  2. 6. A flat surface that is infinitely large and with zero thickness
  3. 9. An angle that has measure more than 90° and less than 180°.
  4. 10. A polygon that has all interior angles less than 180°
  5. 11. rays Two rays with a common endpoint that point in opposite directions and form a straight line.
  6. 16. The distance around the outside of a plane figure.
  7. 18. Any of the individual surfaces of a solid object.
  8. 20. A closed plane figure for which all sides are line segments. polyhedron A solid with no curved surfaces or edges. All faces are polygons and all edges are line segments.
  9. 21. angles opposite one another at the intersection of two lines.
  10. 24. reach a conclusion.
  11. 25. A precise location or place on a plane. Usually represented by a dot.
  12. 26. All points between two given points (including the given points themselves).
  13. 28. terms point, line, and plane
  14. 29. Lying in the same plane. For example, any set of three points in space are coplanar.
  15. 31. When two lines intersect, four angles are formed. The angles that are directly opposite to each other
  16. 33. In a right triangle (one where one interior angle is 90°), It is always the side opposite the 90° angle.
  17. 36. A line segment between two points on the circle or sphere which passes through the center.
  18. 37. A complete circular arc. collinear Lying on the same line.
  19. 40. Exactly equal in size and shape.
  20. 41. A line segment between the center and a point on the circle or sphere.
  21. 42. A polyhedron with a polygonal base and lateral faces that taper to an apex.
  22. 43. Two distinct coplanar lines that do not intersect.
  23. 45. Two rays sharing a common endpoint. Angles are typically measured in degrees or radians.
  24. 46. A part of a line starting at a particular point and extending infinitely in one direction.
Down
  1. 1. A unit of angle measure equal to of a complete revolution.
  2. 3. An assertion that can be proved true using the rules of logic.
  3. 4. where the two rays making up the angle meet.
  4. 5. A three-dimensional geometric figure with parallel congruent bases. The bases can be shaped like any closed plane figure (not necessarily a circle) and must be oriented identically.
  5. 7. Two Angles that add up to 90 degrees. They don't have to be next to each other, just so long as the total is 90 degrees.
  6. 8. a written account of the complete thought process that is used
  7. 10. A three dimensional figure with a single base tapering to an apex. The base can be any simple closed curve.
  8. 12. A statement accepted as true without proof.
  9. 13. The geometric figure formed by two points. the straight path connecting two points and extending beyond the points in both directions.
  10. 14. 2 angles that add up to 180 degrees
  11. 15. a set of values that show an exact position.
  12. 17. angle angle that is 90 degrees
  13. 19. a polygon such that there is a straight line that cuts it in four or more points
  14. 20. Lines that form a 90° angle.
  15. 22. Two angles in a plane which share a common vertex and a common side but do not overlap.
  16. 23. A three dimensional solid consisting of all points equidistant from a given point.
  17. 27. To draw a shape, line or angle accurately using a compass and straightedge (ruler).
  18. 30. A line segment, line, or plane that divides a geometric figure into two congruent halves.
