Lesson 30: Drawing a Triangular Prism

Instructions: Practice drawing three-dimensional triangular prisms. A triangular prism is a three-dimensional form with straight sides and a triangular cross-section.

Materials: Ruler, drawing paper, drawing implements such as pencils, fine-tipped pens or markers, or charcoal.

Keywords: Triangular, prism, triangular prism, cross-section, three-dimensional

Step 1: Draw two identical triangles, one above and to the right of the other as shown below.
Step 2: Draw vertical lines to connect the three points of the triangles as shown below.
Step 3: Erase the dotted lines as shown below.
See below a finished triangular prism.
Step 4: Practice drawing additional triangular prisms.

Step 5: With a fresh piece of paper, draw anything you wish, but incorporate at least one triangular prism into your artwork. Use glue, scissors, colored paper, markers, paint, or anything else you desire to create your artwork.

See below the painting 'The Knife Grinder or Principle of Glittering' by artist Kazimir Malevich. Examine the painting and find the triangular prisms. What other three-dimensional shapes can you identify?
