Across
  1. 1. (π) The numerical value of the ratio of the circumference of a circle to its diameter of approximately 3.14159.
  2. 2. A solid composed of two congruent circles in parallel planes, their interiors, and all the line segments parallel to the axis with endpoints on the two circles
  3. 6. A curve formed at the interior intersection between two or more surfaces
  4. 8. The curved upper surface of a liquid column that is concave when the containing walls are wetted by the liquid and convex when not.
  5. 11. The number of square units required to cover a surface.
  6. 12. triangle A triangle with one angle that is greater than 90 degrees.
  7. 13. axis The lines of intersection created from three mutually perpendicular planes, with the three planes’ point of intersection at the centroid of the part
  8. 18. The amount of three-dimensional space occupied by an object or enclosed within a container.
  9. 19. The measure of mass density is a measure of mass per volume
  10. 21. area The squared dimensions of the exterior surface.
  11. 23. A four-sided polygon with both pairs of opposite sides parallel.
  12. 24. Each angular point of a polygon, polyhedron, or other figure.
  13. 27. A triangle located round a polygon such as a circle. 2 To draw a figure around another, touching it at points but not cutting it
  14. 29. A straight line from the center to the circumference of a circle or sphere.
  15. 30. A polygon with three sides.

  18. 33. A regular polygon with four equal sides and four 90 degree angles.
Down
  1. 1. A solid geometric figure whose two ends are similar, equal, and parallel rectilinear figures, and whose sides are parallelograms.
  2. 3. A straight line passing from side to side through the center of a circle or sphere.
  3. 4. A round plane figure whose boundary consists of points equidistant from the center
  4. 5. An imaginary line through a body, about which it rotates. 2. An imaginary line about which a regular figure is symmetrically arranged. 3. A fixed reference line for the measurement of coordinates.
  5. 7. triangle triangle that contains only angles that are less than 90 degrees
  6. 9. To draw a figure within another so that their boundaries touch but do not intersect
  7. 10. Two or more exterior surfaces rounded at their intersections.
  8. 11. The amount of rotation needed to bring one line or plane into coincidence with another, generally measured in radians or degrees.
  9. 14. A parallelogram with 90 degree angles. A square is also a rectangle
  10. 15. A shape generated by a point moving in a plane so that the sum of its distances from two other points (the foci) is constant and equal to the major axis
  11. 16. block A table located in the bottom right-hand corner of an engineering drawing that identifies, in an organized way, all of the necessary information that is not given on the drawing itself.
  12. 17. polygon A polygon with equal angles and equal sides.
  13. 20. A four-sided polygon
  14. 22. of gravity A 3D point where the total weight of the body may be considered to be concentrated

  17. 28. A 3D point defining the geometric center of a solid
