  2. 5. Any plane figure bounded by straight lines.
  3. 6. The number of square units required to cover a surface.
  4. 7. 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.
  5. 10. A triangle that has a 90 degree angle.
  6. 12. A triangle that contains only angles that are less than 90 degrees.
  7. 13. Each angular point of a polygon, polyhedron, or other figure.
  8. 14. 1. 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.
  9. 15. The amount of three-dimensional space occupied by an object or enclosed within a container.

  15. 23. The lines of intersection created from three mutually perpendicular planes, with the three planes’ point of intersection at the centroid of the part.
  16. 25. The numerical value of the ratio of the circumference of a circle to its diameter of approximately 3.14159.
  17. 26. A 3D point defining the geometric center of a solid.
  18. 27. A straight line passing from side to side through the center of a circle or sphere.
  19. 29. A polygon with equal angles and equal sides.
  20. 31. The curved upper surface of a liquid column that is concave when the containing walls are wetted by the liquid and convex when not.

  22. 34. The amount of rotation needed to bring one line or plane into coincidence with another, generally measured in radians or degrees.

  1. 1. 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
  2. 3. The squared dimensions of the exterior surface
  3. 4. Two or more exterior surfaces rounded at their intersections.
  4. 8. 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. Also referred to as a title strip.
  5. 9. A four-sided polygon with both pairs of opposite sides parallel.

  13. 32. A round plane figure whose boundary consists of points equidistant from the center
