Use the mouse to zoom in and out of the prism.
When moving the sliders, the parameters a and h change.
1. Turning the prism, look at the projections of the prism - from above, in front and from the side. By changing the parameters of the prism a and h, pay attention to the changes in the images of orthogonal projections of the prism.
2. Pay attention to the orthogonal projections of points A and B located on the outer surface of the prism and their location on the images of the projections of the prism.
3. Moving point A along the site of the prism, pay attention to the change in its orthogonal projections on the prism sides.

A polyhedron net is a corresponding arrangement of non-intersecting edge-connected polygons in a plane that can be folded (along the edges) to form a three-dimensional polyhedron figure.
Use the animation button or the slider to get the net of this prism.
And follow the dimensions of the net polygons and how the dimensions are related to the prism parameters.
2.2.1.3. GeoGebra link
1. Use the animation button or the slider to get the prism surface. When changing the prism parameters a and h, pay attention to the change in the dimensions of the prism net.
2. Pay attention to the position of points A and B, located on the outer surface of the prism, and their location on the net of the prism.
3. Moving point A along the site of the prism, pay attention to the change in its location on the net of the prism.
2.2.1.4. GeoGebra link
1. Use the slider for a prism with equilateral polygons at the base. When you change the prism parameter h, please pay attention to the change in the dimensions of the prism surface.
2. Pay attention to the position of point A, located on the side of the prism surface, and its location on the prism surface image.
3. Moving point A along the side of the prism, pay attention to the change in its position on the surface of the prism.

The wedge is also a prism, but its base is a right triangle with legs a and b.
1. Use the slider to change parameters a and b. When changing the wedge side parameters a, b and h, note the change in the dimensions of the wedge.
2. Using the animation button or the slider, note the change in the wedge surface image.
3. Moving point B along the side of the wedge, pay attention to the change in its position on the surface of the wedge.
2.2.1.6.1. To consolidate the information received, check how you have mastered the receipt of orthogonal projections of the prism, points on its sides and the surface image.
