Across
  1. 2. The flat, two-dimensional figure that can be folded to form a three-dimensional figure.
  2. 3. A closed shape with straight sides (e.g., triangle, square, rectangle, parallelogram, hexagon).
  3. 9. Lines that intersect to form right angles
  4. 10. A three-dimensional solid shape with six faces that are all rectangles.
  5. 11. A perpendicular line segment from the vertex of a triangle to the opposite side (the base). In a parallelogram, it is a perpendicular line segment from the base to its opposite side; the height of the figure.
  6. 12. The measure of the total area occupied by the surface (outside) of a three-dimensional object. It is measured in square units.
  7. 13. The amount of space inside a three-dimensional object; measured in units cubed.
  8. 14. lines that never intersect and are always the same distance apart
  9. 15. The number of square units (e.g., square feet) that make up the inside of a two-dimensional shape.
Down
  1. 1. A three-dimensional shape that has a rectangular base and triangular faces that meet at the apex, which is the point, or vertex, farthest from the base.
  2. 4. A figure that can be divided into more than one basic shape. For example, the trapezoid is composed of a square and a triangle.
  3. 5. The distance around a two-dimensional shape.
  4. 6. A quadrilateral with two pairs of parallel sides.
  5. 7. A 4-sided, closed figure.
  6. 8. The side of a figure that is perpendicular to the altitude; the bottom of the shape.
