Ans. Geogebra is a free, open source and multiplatform software that combines dynamic geometry , algebra, calculus, spreadsheet, graphing and statistics.Geogebra is one easy - to use package. The name , GeoGebra is derived from Geometry and Algebra. GeoGebra was created by Markus Hohenwarter in 2001-02 as part of his Masters and PhD project. GeoGebra is backward compatible in sense that files created with older version should open in later versions. Sometime we make changes which will cause files to behave differently.

- If you align the radius to be an altitude of the triangle (perpendicular to one its sides), you see the triangle and radius intersect in the midpoint of the radius. This means the chord is long enough precisely when the point on the radius is closer to the center than the midpoint. And this is independent of the radius angle

It is an open source application and is freely available for non-commercial use. There are currently versions available for Windows, Mac OS X, Linux and other java-enabled platforms 4. Drop a perpendicular from the incenter to any side. This gives a radius. 5. Construct the point of intersection between the side and perpendicular. 6. Construct a circle that has center of the incenter and the intersection point on the circle itself. This is the incircle. The GeoGebra construction follows the same pattern. 1 I'm having a bit of a mind blank on this at the moment. I've got a problem where I need to calculate the position of points around a central point, assuming they're all equidistant from the center and from each other GeoGebraWiki is a free pool of educational materials for GeoGebra.
