Across
- 3. the total distance around the outside of a polygon. This distance is obtained by adding together the units of measure from each side.
- 5. to arrange (something or someone) again in a different way
- 7. is the number of square units that covers all the faces of the polyhedron, without any gaps or overlaps.
- 9. is a line drawn from the center of any polygon to the midpoint of one of the sides
- 12. is a type of polyhedron that has two bases that are identical copies of each other. The bases are connected by rectangles or parallelograms.
- 14. for each side of a triangle, there is one vertex that is not on that side.
- 16. a triangle with two sides of equal length
- 19. two lines or line segments intersecting to form a right angle.
- 21. a unit of measure describing how much space a substance occupies or the capacity of a container, provided in cubic units.
- 22. the shortest distance from the base of the shape to the opposite side (for a parallelogram) or opposite vertex (for a triangle). We can show it in more than one place, but it will always be perpendicular to the chosen base.
- 23. is the number of square units that covers a two-dimensional region, without any gaps or overlaps.
- 25. a triangle with one right angle.
- 26. is a two-dimensional figure that can be folded to make a polyhedron
Down
- 1. each straight side of a polygon
- 2. is a point where two or more edges meet.
- 4. means “take apart.”
- 6. is a type of polygon that has 4 sides.
- 8. means “put together.”
- 10. is a type of polyhedron that has one base. All the other faces are triangles, and they all meet at a single vertex.
- 11. is a closed, two-dimensional shape with straight sides that do not cross each other.
- 13. an angle equal to 90°.
- 15. is a type of quadrilateral that has two pairs of parallel sides.
- 17. each flat side of a polyhedron
- 18. a triangle with three unequal sides.
- 20. is a closed, three-dimensional shape with flat sides.
- 24. is the space inside of a shape.
