Earlier I received help with a geometry problem: I needed to learn how to manually calculate circles inscribed into triangles. Now that I have that done, I am trying to rework the problem in MuPad.

For the most part, I was able to get what I needed in Maple using this document:

geometry/incircle - Maple Help

I used the output I got from Maple to plot the problem in MuPad , and it was beautifully simple (couldn't get the plot in Maple to work).

The problem is, I cannot actually do the computation in MuPad.

Does anyone have any insight on how to input coordinates, create the triangles, then calculate the radius and center of the inscribed circle?

I have done a lot of research but it seems that the way MuPad handles input is not as straightforward as other packages. I've researched incenters, triangulations, etc and I'm lost.

Thanks in advance for any helps, hints, or sympathies
