Sometimes we do not have a full prism, but instead a truncated one. In this case the surface development (or net) will be slightly different. This is explained in detail in the video attached below.

To cover this lesson please follow these steps:

1. Print out the handouts in the attached file.
2. Follow the instructions of the video and complete both exercises on pages 1 and 2.
3. Check your drawings against the answers in the video..

Congratulations!
Now you can draw the developments of solid prisms.
