Isometric Drawing of a Square-Based Pyramid
Construct a model of a square-based pyramid using drinking straws
and masking tape or other materials. Use isometric dot paper or The
Geometer’s Sketchpad® to sketch an isometric perspective drawing of
the pyramid.
Solution
First, draw the base. The base will appear as a diamond shape. Select a
point in line with two opposite vertices to be the apex of the pyramid.
Complete the pyramid by drawing the sides.
