For example, like if you know the triangle with sides' length 4,6 and 9, how can I know the incircle's area with sage?Fri, 31 Aug 2018 09:52:50 -0500http://ask.sagemath.org/question/43536/how-can-i-describe-incircles-and-calculate-its-area-with-sage/Answer by nbruin for <p>How can I describe incircles and calculate its area with sage?</p>

http://ask.sagemath.org/question/43536/how-can-i-describe-incircles-and-calculate-its-area-with-sage/?answer=43538#post-id-43538That's more a mathematics question than a question about sage. References to and derivations of a nice formula that express the radius of the incircle in terms of the area and perimeter of the triangle are easy to find. Once you have the formulas, it's easy to type them into sage.
If you're interested in making pictures of triangles and their incircles, geogebra is probably a better tool.Fri, 31 Aug 2018 10:49:26 -0500http://ask.sagemath.org/question/43536/how-can-i-describe-incircles-and-calculate-its-area-with-sage/?answer=43538#post-id-43538Comment by pizza for <p>That's more a mathematics question than a question about sage.
