Use interactive GeoGebra exercises to recognize as orthogonal projections of different shapes as to see their cross-sections.
GeoGebra exercises are easy to use for zooming and turning with the mouse on the left side, moving horizontal and vertical planes, getting orthographic projections by a slider.

3.2.1. Exercises with polyhedra
3.2.2. Exercises with rotating shapes
After the exercises are completed, construct and draw the orthogonal and axonometric projections of the cut shapes group.
The first task is to use the video to draw orthogonal and axonometric projections of a group of simple shapes with a cutting plane.
