GeoGebra
You can use GeoGebra to draw pyramids in 3D space by following one of these methods:
-
If you want to draw an arbitrary pyramid, choose Item 4.
If you know the base, and either the top point or height of the pyramid, choose Item 4.
GeoGebra Instruction 1
Drawing a Pyramid Using the Pyramid Tool
- 1.
- Open
Algebra Viewand3D Graphicsunder
Viewin
Menu. - 2.
- Click on
Pyramid
. - 3.
- Make a polygon in the -plane that will serve as the base of the pyramid.
- 4.
- Adjust the top of the pyramid in the desired position. If you are not satisfied with the pyramid, you can always adjust the positions of the points.
GeoGebra Instruction 2
Pyramid Given by the Base and Either Top or Height
- 1.
- Open
Algebra ViewandGraphics Viewin Viewunder Menu. - 2.
- Click on
Polygon
and make a triangle or a square that will serve as the base of the pyramid. - 3.
- In
Algebra View, typePyramid(Polygon, Point)
where you replace
Polygonwith the name of the base, and replacePointwith a desired point that will serve as the top of the pyramid. You can see what the pyramid looks like in3D Graphics. - 4.
- Alternatively, you can type
Pyramid(Polygon, Height)
in
Algebra Viewwhere you replaceHeightwith a number that will serve as the height of the pyramid.
Example 1
Draw a pyramid in GeoGebra using a square with side lengths of 4, and a height of 5
Follow Item 4 for solving this exercise. Draw a square by using Polygon and then use
Pyramid(Polygon, Height)
to draw the pyramid.
