2.2.2.1. GeoGebra link
Use the mouse to zoom in and out of the pyramid.
When moving the sliders, the parameters h and base polygon sides change.
1. Turning the pyramid, look at the shape's projections - from above, in front and from the side. By using sliders, 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 sides of the pyramid and their location on the images of the top, front views projections of the pyramid.
3. Moving point A along the site of the pyramid, pay attention to the change in its orthogonal projections.
2.2.2.2. GeoGebra link
1. Move the slider to obtain a development of the side surface of the correct pyramid. Please pay attention to the edges of the base and side surface of the pyramid - it is on their lengths that the size of the entire development of the pyramid depends.
2. Move point A along the side of the pyramid, while paying attention to the change in the size of its movement relative to the side of the base.
2.2.2.3. Watch the first short video showing different images of the same pyramid net. Since the net of the pyramid consists of a base polygon and identical triangles, it is rational to use an arc whose radius is the edge of the pyramid to construct its net.
2.2.2.4. To consolidate the information received, check how well you got information about the pyramid.
2.2.2.5. And to consolidate the information received, check how well the you got information about pyramid.
