Tool - 3.1.1

Create a GeoGebra tool that accepts two points as input objects and whose output object is an equilateral triangle with the given points as the endpoints of one side. Call this tool "Equilateral". When you are satisfied that you created the tool correctly, use the hamburger menu to "File-Save". Name your file "Tools".

Tool - 3.1.2

Create a GeoGebra tool that accepts two points as input objects and whose output is a square with the given points as the endpoints of one side. Name the tool Square. When complete, save the file again with the name Tools. The idea is that we will continue to build a Tools template so that each time we need a tool, we can access the tools already made.

Tool - 3.1.3

Create a GeoGebra tool that accepts a segment as its input object and constructs a circle with the given segment as diameter. Save your tool with the name Diameter. Then save the file as Tools.

Tool - 3.1.4

Create a GeoGebra tool that constructs the centroid of a triangle. Your tool should accept three vertices of a triangle as input objects and produce the triangle and the centroid G as output objects. The tool should not display the intermediate objects (such as the medians) that were used in the construction of G. Call this tool Centroid, then save the file as Tools.

Tool - 3.1.5

Create a GeoGebra tool that constructs the altitudes of a triangle. Your tool should accept three vertices of a triangle as input objects and produce the triangle and the altitudes as output objects. Make the tool so that the altitudes always appear in the same distinctive color. Save the tool as Altitudes, then save the file as Tools.

Tool - 3.1.6

Make a GeoGebra tool that constructs the orthocenter of a triangle. Your tool should accept three vertices of a triangle as input objects and produce the triangle and the orthocenter as output objects. The tool should not display the intermediate objects that were used in the construction. Name the tool Orthocenter, then save the file as Tools.

Tool - 3.1.7

Make a GeoGebra tool that constructs the circumcenter of a triangle. Your tool should accept three vertices of a triangle as input objects and produce the triangle and the circumcenter as output objects. Name this tool Circumcenter, then save the file as Tools.[br][br]Before leaving section 3.1, ensure that your tool repository contains all 7 tools you just created with the proper names. If you made a mistake in making a tool, ensure you delete the incorrect tool.

Use this applet for 3.1.1-3.1.7 - When you have completed all tools with proper names, save the applet as Tools. Then clear the applet and use the hamburger menu to load the Tools applet.
