today i was building a right cone for my geometry homework.after building the cone, i started to think what shape the net of an oblique cone (cones with circular base which the axis does not pass perpendicularly through the center of the base) would look like. I searched on the internet and I found this(from here):
i'm interested to know why the net has a shape like this.
Does this shape has an special name?
And my more general question is: what is the process to draw net of a 3d object?
