Chapter 23 - DEVELOPMENTS

     

  1. Which types of geometric solids would use the parallel line development technique for creating a surface development?


  2. Which types of geometric solids would use the radial line development technique for creating a surface development?


  3. Are the plane surfaces on the development of a prism and pyramid exactly true size?


  4. Are the plane surfaces on the development of a cylinder and cone exactly true size?


  5. Which of the following solids is the most difficult and least accurate surface development: prism, cylinder, pyramid, cone, sphere?


     

  6. How many radial elements would you need to create on a cone so its surface development was perfectly accurate?


  7. Are the triangles created on a transition development true size or approximations of true size?


  8. When creating the surface development of a truncated pyramid, which of the radial elements extend beyond the actual: surface boundaries of the pyramid?


  9. Is the stretch-out line of a cylinder's surface development exact size or approximate?


  10. Which development method of a sphere would have the most accurate representation of the North Pole?
