Down
- 1. A three-dimensional figure with faces that are polygons
- 2. Having the same size and shape
- 3. A pair of opposite congruent angles formed by intersecting lines. Since they are congruent, the measures of the angles are equal
- 5. an angle measuring more than 90 degrees and less than 180 degrees
- 6. a three-dimensional representation of an object that is too large or too small to be built at actual size
- 7. the ratio that compares the measurements of a drawing or model to the measurements of the real object
- 8. a triangle with one obtuse angle
- 13. A line segment where two faces of the polyhedron meet
- 14. two angles whose measures have a sum of 90 degrees
- 16. A drawing that is used to represent objects that are too large or too small to be drawn at actual size.
- 19. A polyhedron with two parallel congruent faces called bases
- 21. A three-dimensional figure with two parallel congruent circular bases connected by a curved surface.
- 22. have the same vertex, share a common side, and do not overlap.
- 24. A three dimensional shape with a circular base and a vertex opposite the base
- 25. A two-dimensional flat surface that extends in all directions
- 27. the intersection of a solid and a plane. Fruit ninja
