(1) Because the direction of the slope did not coincide with the axis of the view, the architect made the plan in the shape of a parallelogram .(2) The building is in the form of a rectangular parallelogram , 294 feet five inches long by 219 feet nine inches wide, covering an area of 7,188 square yards.(3) Four congruent sides lie on two parallel lines, and pairs of these sides define parallelograms of equal area.(4) His vertical stripes have been put onto a slant, and whittled down to slender triangles or widened into parallelograms or pyramids.(5) This caused a deflection, which if it be analyzed, both directions taken together would be found to be a parallelogram of forces .(6) Parallelogram of Forces is the famous theorem that can be used to determine the resultant of two forces acting at a point.(7) In the deformation, the parallelograms always remain parallelograms , because their opposite sides remain equal, but the angles change.
