I want to make a dome (1/2 sphere) that is made up of 10 metal
"triangular" sections. It will not be a true 1/2 sphere. Each
metal section will be bent in only one direction and will be straight
in the other. The base and each horizontal cross section will be a
Decagon (10 equal sides). Each vertical cross section will be some
sort of a 1/2 circle. I am trying to figure out how to make the 10
"triangles" so that the sides will touch when bent.


The name of the shape (item) you're trying to make is "gore". Do some
searches on calculating the dimensions of "gores". They're most made of
fabric for making hot air balloons and parachutes of the older spheric or
parabolic geometries.

Thank you so much. I found a few good pages that helped me
tremedously.
