| Using parallelograms to define affine transformations may be a mixed blessing. |
|
| In particular books one and two set out basic properties of triangles, parallels, parallelograms, rectangles and squares. |
|
| The works were composed of very elongated parallelograms and regular trapezoids. |
|
| It was parallel and modern and ran level with lines of mountain, it was squares to be bisected and parallelograms and rhomboids. |
|
| Squares and rectangles are the main planning module and these warp into parallelograms to accommodate the natural topography. |
|
| For example, Angel consists of three layers of open triangles, trapezoids, parallelograms and pentagons, once again made of wood. |
|
| This requires that their underlying lattices be based on triangles, parallelograms, or hexagons. |
|
| In the deformation, the parallelograms always remain parallelograms, because their opposite sides remain equal, but the angles change. |
|
| His vertical stripes have been put onto a slant, and whittled down to slender triangles or widened into parallelograms or pyramids. |
|
| Four congruent sides lie on two parallel lines, and pairs of these sides define parallelograms of equal area. |
|
| Analysts also use a variety of symbols, such as parallelograms, pentagons, and others, to depict different types of events and activities. |
