Note: Your custom tool is still part of the tool bar.Ģ. GeoGebra fills in the corresponding input objects for your tool automatically (our example: points A, B and C). Click the Next > button in order to activate tab Input Objects.ĥ. Specify the output objects of your new tool by either clicking on the desired output object on the drawing pad (our example: segment c) or selecting it from the drop down menu (click on the little arrow next to the input field).Ĥ. By default, tab Output Objects is activated.ģ. In menu Tools click on Create New Tool… to open the Create New Tool dialog window.Ģ. Change the labeling setting to All New Objects (menu Options – Labeling).Ĭreate line a through two points A and B.Ĭreate perpendicular line b to line a through point C.Ĭonstruct intersection point D of lines a and b.ĭrag points A, B and C to check your construction.Ĭhange the color of segment c and hide the labels of all objects.ġ.Before you can create your custom tool you need to construct all the objects required for your tool.
Let’s now create a tool that determines the minimal distance between a line and a point (e.g. This means that you can extend the toolbar by creating your own tools. GeoGebra allows you to create custom tools. Come up with an explanation that helps your students understand the theorem of Pythagoras. Insert text that describes the Pythagorean theorem.Įxport your construction as a dynamic worksheet. Insert static text3: c^2 and attach it to the midpoint of the corresponding square.įormat the text to match the color of the corresponding squares. Insert static text2: b^2 and attach it to the midpoint of the corresponding square. Hint: Click on diagonal opposite vertices of each square. Insert static and dynamic text into your construction that helps to understand the Pythagorean theorem where a and b are the legs and c is the hypothenuse of a right triangle.Ĭreate the midpoints of all three squares. Repeat steps 8 to 15 for side AB of the triangle.ĭrag the vertices of the right triangle to check if your squares are correct.Įnhance your construction using the Properties dialog.
Repeat steps 8 to 15 for side AC of the triangle. Intersect the circle f and the perpendicular line d to get intersection point D.Ĭreate a parallel line g to segment BC through point D.Ĭreate intersection point E of lines e and g. Hint: Click in the middle of the polygon to create all angles.ĭrag point C to check if your construction is correct.Ĭreate a perpendicular line d to segment BC through point C.Ĭreate a perpendicular line e to segment BC through point B.Ĭreate a Circle f with center C through point B. Change the labeling setting to New Points Only (menu Options – Labeling).Ĭreate semicircle c through points A and B.8 Challenge of the Day: Euler’s Discovery.
