3D Algebra and Tools

Integration with Geogebra 3D using Algebra

Step 1:

Select the “Insert” button on the toolbar and select Geometry 3D.

Step 2:

A graph box will show up on your Canvas. Click on the Algebra button (calculator icon).

Step 3:

Select the Input box and type in the desired expression. You can also click on the keyboard logo in the bottom left of the graph box to get access to more algebraic symbols.

Step 4:

Once you have inserted the desired graph equation in the input box, a corresponding 3D graph will appear in the graphing space to the right. You can click and drag your mouse to move the 3D graph around and change its placement.

3d Tools: 3D Geometry

Step 1:

Select the “Insert” button on the toolbar, and select Geometry

Step 2:

Select the “Insert” button on the toolbar, and select Geometry 3D

Step 3:

A graph box will show up on your Canvas. Click on the Tools button (circle and triangle icon)

Adding a Point

To add a point on the graphing space, select Point, then click on the blank graphing area. A point will be displayed at the area you’ve clicked.

Adding a Pyramid

To add a pyramid on the graphing space, select Pyramid, then select the 3+ points you want to build your Pyramid base on, then after clicking the initial point to close the base, create a point for the top vertex (apex). A pyramid will be displayed based on the points you’ve selected.

Inserting a Cube

To add a cube on the graphing space, select Cube, then select the 2 points you want to build your Cube on any 2 axes. A cube will be displayed based on the 2 points you’ve selected.

Inserting a Sphere

Step 1:

To add a sphere on the graphing space, select Sphere: Center & Point

Step 2:

Click on a point on the 3D graphing area where you want the center of the sphere to be, then drag your mouse further or closer to the center to adjust the diameter of the sphere. When the desired shape is achieved, click anywhere on the sphere to solidify the shape.

Inserting A plane

To add a plane on the graphing space, select Plane through 3 Points. Then select the 3 points you want to build your Plane on the axes. A plane will be displayed based on the 3 points you’ve selected.

Intersecting Two Surfaces

Once you have built two surfaces that are intersecting, you can see the points where the two surfaces intersect by clicking on Intersect Two Surfaces, selecting both surfaces, then you can see all the points where the two surfaces overlap.

To see how you can build different surfaces (e.g., pyramid, cube, plane), please see the sections above.

Moving Objects

You can move any object on the graphing space by selecting Move, clicking on the desired object, then moving it to the desired placement.
