The steps to create the inscribed circle of triangle ΔABC using GeoGebra includes;
1) Clicking on the <em>Geometry </em>link, under <em>Powerful Math Apps</em> group
2) On the opened <em>Geometry </em>page click on the <em>Polygon </em>icon and follow the instructions that come up, which is <em>Select all vertices and then the first vertex </em>(selected) <em>again </em>(a second time)
3) Once the triangle is created, select the <em>Angle Bisector</em><em> </em>icon, under the <em>Construct </em>group; A message will appear, asking to <em>Select three points or two lines</em>, select three vertex, of the triangle created with a mouse click, with the vertex <em>A</em> in the center, such as <em>BAC</em>, or <em>CAB</em> a straight line representing the angle bisector of angle ∠A is created
4) Repeat the above to create the angle bisector of angle ∠B
5) Click on the <em>Point</em> button under the Basic Tools group, then click on the intersection of the two angle bisectors created above, the point will be automatically labelled point <em>D</em>
6) Click on the <em>Perpendicular Line</em>, icon under the <em>Construct </em>group, then click on point <em>D</em>, and then the line <em>AB</em> to draw the perpendicular from <em>D </em>to <em>AB</em>
7) Click on the point <em>Point </em>icon and then the intersection point of the perpendicular from <em>D</em> and <em>AB</em> to label the point <em>E</em>
8) Click on the <em>Circle with Center</em> basic tool and then points <em>D</em> and <em>E</em> above, to create the inscribed circle of triangle ΔABC
