Working in 3D
Construct a cube below. Then construct its net. Open and close its net a few times.
Nets
In Geometry a net is a two-dimensional pattern that represents the faces of a three-dimensional shape when laid out flat, meaning you can cut out the net and fold it to create the 3D shape; essentially, it's like seeing the "unfolded" version of a solid figure on a flat surface.
How many faces, edges, and vertices does a cube have? Use the [b]Cube[/b] tool to make a pyramid then use the [b]Net [/b]tool to identify its characteristics.
How many faces, edges, and vertices does a triangular pyramid have? Use the [b]Pyramid[/b] tool to make a pyramid then use the [b]Net [/b]tool to identify its characteristics.
Which body is described with this definition?
"Completely round [geometric] body, where all points of the surface are equidistant from the center."
What geometric body would have a net like the one shown below? Try to imagine what it would look like if this 2D was folded into 3D. Make the solid in your 3D by clicking [b]More[/b] in the tools bar then scrolling down to [b]Solids[/b]. Try out different shapes if you are unsure, then make a [b]Net.[/b][br] [img]data:image/png;base64,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[/img]
