Other problems show how to find the area of rectangles, triangles and trapezoids. Under the inclusive definition, all parallelograms (including rhombuses, rectangles and squares) are trapezoids. Thus range search becomes the problem of returning all rectangles intersecting the search rectangle. Excavations reveal examples based on squares, rectangles and shapes similar to the letter D. Photoshop provides an array of shape tools including rectangles, rounded rectangles, ellipses, polygons and lines. It consists of some symbols such as arrows, circles, diamonds, boxes, ovals, or rectangles. The blocks can be rectangles or parallelograms. The user inserts and manipulates primitive shapes such as rectangles, vertical and horizontal lines. This transforms the side rectangular faces into crossed rectangles. The vertices of a regular icosahedron are those of three mutually orthogonal golden rectangles. Larger unbounded rectangles of color punctuate the design, some with smaller concentric rectangles inside them. This is possible for acute trapezoids or right trapezoids (rectangles). Circular plan shapes lack the simple modularity provided by rectangles. Now cut one square into two rectangles. "Ingberlach" are ginger candies shaped into small sticks or rectangles.
