To create a general triangle given known sides and angles the following
family of functions are useful: @racket[triangle/sss],
@racket[triangle/ass], @racket[triangle/sas], @racket[triangle/ssa],
@racket[triangle/sss], @racket[triangle/sss], and, @racket[triangle/sss].
To create a triangle given known sides and angles, the following
