Creating a Line Segment in GeoGebra

This guide provides a comprehensive overview of constructing line segments in GeoGebra. 

First, let's clarify: what exactly is a line segment? It's a portion of a straight line confined between two distinct points, referred to as endpoints. A line segment is devoid of thickness and extends unidirectionally. The segment's length is simply the distance between these endpoints. For clarity, consider segment AB on a plane, where A and B serve as the segment's endpoints.

Creating a Segment in GeoGebra

Access the Segment Tool.

Locate this tool either at the top toolbar or along the side, contingent on your version or display preference.

Within the menu, select the option labeled "Segment".

Determine the First Endpoint: With the "Segment" tool active, tap any spot within the graphic view.

This action will set your segment's initial endpoint. Upon doing so, GeoGebra will automatically label this point. In our demonstration, it's labeled as point A.

Establish the Second Endpoint: Hold and drag your mouse to your desired endpoint location, then release.

 

You've successfully plotted a segment on the graphic canvas.

Adjusting Your Segment

Activate the Pointer Tool.

This tool is readily available in the top menu.

Reposition the Endpoint: Simply click on any segment endpoint, drag to your desired location, and release.

For instance, to move endpoint A, click and drag it to a new location.

Customizing Your Segment

To tweak the segment's appearance, such as its color or thickness, right-click directly on the segment.

In the dropdown menu, opt for "Settings" or its equivalent.

This menu offers a suite of tools for adjusting the segment's aesthetics.

A quick tip: after working with the "Segment" tool, ensure you deselect it, especially if you're transitioning to another tool or interaction mode. This can be achieved by selecting a different tool or simply clicking on an empty space within the workspace.

In wrapping up, this guide has equipped you with the knowledge to proficiently draw and adjust segments in GeoGebra.
