Your drawing should look like the one shown in Figure 1. This will construct point F and G respectively. Also, intersect the BC and the perpendicular bisector. Using the Intersect Two Objects tool, intersect AB and the perpendicular bisector. To construct the perpendicular bisector, select the Perpendicular Bisector tool, click point B and then click point E.ġ0. The number of data points should also be limited to n is less than or equal to 100 data points or the plotting becomes tiresome. Data should be of limited tangle or else the width of the dot plot becomes cumbersome.
If we fold the right corner of the rectangle, where point B will coincide to E, the crease that will be formed will be the perpendicular bisector of BE.ĩ. Geometry Tool - Draw Online Geometric Figures Full-Screen Mode. Display the grid and drag point E to (4,2).
Now, select the Point on Object tool, and click the interior of the polygon This will create point E.Ĩ. In using the Polygon tool, click the points in the following order: A, B, C and D, then A.ħ. Now, using the Polygon tool, construct polygon ABCD. Now, fix the location of the other three points.Ħ. In the Preferences window, select the Basic tab, and check the Fix Object check box. To fix point A, right click on it and click Object Properties to display the Preferences window.ĥ. Now, we fix the location of the points to avoid it being accidentally moved. Type A = (0,4) in the Input bar and then press the ENTER key to construct point A on (0,4). To show labels of new created points, click the Options menu, select Labeling, and then click New Points Only.ģ. Open GeoGebra and select the Algebra & Graphics view from the Perspectives menu.Ģ. You can view the output of this tutorial here.ġ. If you want to follow this tutorial step-by-step, you can open the GeoGebra window in your browser by clicking here. As an alternative, the Point in region tool can be replaced by the New point tool as an alternative in lower versions (see details in the step-by-step instructions). Show the axes, hide the perpendicular bisector, and drag point E to (5,1).Use the Polygon tool to construct triangle FEG. We will use a Point on Object, a which is only available in GeoGebra 4.0 Beta Release, which can be downloaded here. Hide the Axes, drag point E to (5,0) and then intersect the line with AD to construct point H.Drag point E to (1,3) and then Intersect the perpendicular bisector and CD (segment c in the algebra view).This will form point I.: 12. We will represent a rectangular piece of paper with corners ABCD and drag the upper right corner (vertex B) anywhere inside the rectangle. In this tutorial, we are going to use GeoGebra to simulate paper folding.
