| Squares and rectangles are the main planning module and these warp into parallelograms to accommodate the natural topography. |
| His vertical stripes have been put onto a slant, and whittled down to slender triangles or widened into parallelograms or pyramids. |
| In the deformation, the parallelograms always remain parallelograms, because their opposite sides remain equal, but the angles change. |
| For example, Angel consists of three layers of open triangles, trapezoids, parallelograms and pentagons, once again made of wood. |
| Analysts also use a variety of symbols, such as parallelograms, pentagons, and others, to depict different types of events and activities. |
| Four congruent sides lie on two parallel lines, and pairs of these sides define parallelograms of equal area. |
