A shape is two-dimensional; a form has three-dimensional extent. A drawing can suggest a solid form without becoming the actual object. These questions ask about the described object or model, not the physical thickness of the page.

Worked example

A flat circle is a shape; a solid sphere is a form. A picture of a sphere remains a representation.

A flat square is labeled shape. A line drawing suggests a three-dimensional cube labeled form. The cube drawing represents a solid; the page itself is still a flat representation.

Question 4 Study 4 describes a solid cube. Which term applies to that described model?
Question 5 Study 5 describes a flat triangle. Which term applies to that described model?

Make It Your Own

Optional theme: a surprising delivery. Draw a flat shape and a related solid form. Use overlap or value to suggest volume, then explain the difference between the drawing and the object it represents. You may draw, write or tell your idea. Use invented characters and places; no personal information or upload is needed. This activity is not scored.

Reflect on your choices

  • Name the two-dimensional shape and three-dimensional form separately.
  • Explain one intentional choice and one possible alternative.
  • There is no required style or single correct creative response.
