10 A Rhomboides is an obliquangled parallelogramme not equilater 33. d j.
And a Rhomboides is so opposed to an oblong, as a Rhombus is to a quadrate.
So also looke how much the straightening or pressing
together is greater, so much is the inequality of the obtuse and acute angles the greater. As here.
And the Rhomboides is so called as one would say Rhombuslike, although beside the inequality of the angles it hath nothing like to a Rhombus. An example of measuring of a Rhomboides is thus.
11 A Trapezium is a quadrangle not parallelogramme. 34. d j.
