How to draw an unequal parts triangle with equally curved corners?

[gaftalik]

Hi everyone,


How is it possible to draw a triangle with no equal parts such as 8cm x 6cm and have equal adjustable curved corners as much as needed?

I tried the quick shape tool and set the sides to 3 but the most difficult part was to convert to edible shapes and draw it manually and messed up.

Then i tried to draw a rectangle with curved corners and deleted two points to get a triangle shape but i ended up with different curved corners !!

I am using Xara Designer Pro X11.

Thank you for your help!
