  5. 11. A flat surface of a polyhedron
  6. 12. A point where two or more straight lines meet or a point where three or more faces of a 3-D shape meet.
  7. 15. A polyhedron with a polygon base and triangular sides that all meet at a common vertex
  8. 17. an angle measuring more than 0 and less than 90 degrees
  9. 18. An angle that measures exactly 0 degrees.
  10. 20. plural of vertex
  11. 23. all sides are the same length and angles have the same measure
  12. 26. a triangle with two sides the same length and two angles congruent to each other
  13. 28. a triangle with no congruent sides
Down
  1. 1. A three-dimensional figure with faces that are polygons
  2. 2. Having the same size and shape
  3. 3. A pair of opposite congruent angles formed by intersecting lines. Since they are congruent, the measures of the angles are equal
  4. 5. an angle measuring more than 90 degrees and less than 180 degrees
  5. 6. a three-dimensional representation of an object that is too large or too small to be built at actual size
  6. 7. the ratio that compares the measurements of a drawing or model to the measurements of the real object
  7. 8. a triangle with one obtuse angle
  8. 13. A line segment where two faces of the polyhedron meet
  9. 14. two angles whose measures have a sum of 90 degrees
  10. 16. A drawing that is used to represent objects that are too large or too small to be drawn at actual size.
  11. 19. A polyhedron with two parallel congruent faces called bases
  12. 21. A three-dimensional figure with two parallel congruent circular bases connected by a curved surface.
  13. 22. have the same vertex, share a common side, and do not overlap.
  14. 24. A three dimensional shape with a circular base and a vertex opposite the base
  15. 25. A two-dimensional flat surface that extends in all directions
  16. 27. the intersection of a solid and a plane. Fruit ninja
