| He arranges thin rectangles, squares, triangles and trapezoids in complex patterns on the wall. |

| And if you tilt your camera to take a picture of a building or a monument, vertical lines will converge and rectangles turn into trapezoids. |
| The works were composed of very elongated parallelograms and regular trapezoids. |
| Wood blinds, meanwhile, can fit a variety of applications, including quarter arches, full arches, angles, trapezoids, hexagons and triangles. |
| It is also relatively easy to make, as long as you don't get too fussed about perfect trapezoids of bread and the delicate art of construction. |
