Example of the use of descriptive geometry to find the shortest connector between two skew lines. The red, yellow and green highlights show distances which are the same for projections of point P. Given the X, Y and Z coordinates of P, R, S and U, projections 1 and 2 are drawn to scale on the X-Y and X-Z planes, respectively.

To get a true view (length in the projection is equal to length in 3D space) of one of the lines: SU in this example, projection 3 is drawn with hinge line H2,3 parallel to S2-U2. To get an end view of SU, projection 4 is drawn with hinge line H3,4 perpendicular to S3-U3. The perpendicular distance d gives the shortest distance between PR and SU.
Figure 2. Box-plot with whiskers from minimum to maximum Figure 3. Same box-plot with whiskers drawn within the 1.5 IQR value. A boxplot is a standardized way of displaying the dataset based on the five-number summary: the minimum, the maximum, the sample median, and the first and third quartiles.
Trim line – Clear line on the side of a valley marking the most recent highest extent of the glacier; Truncated spur – Ridge that descends towards a valley floor or coastline that is cut short; Tunnel valley – Glacial-formed geographic feature; Valley – Low area between hills, often with a river running through it
The second line consists of two adjectives describing the subject, and the third line contains three verbs ending in the suffix ing which are related to the subject. A fourth line then has four nouns relating to the subject. The fifth returns to three verbs, the sixth two adjectives, and the final line a synonym of the subject. [3]
Ekphrasis or ecphrasis (from the Greek) is a rhetorical device indicating the written description of a work of art. [1] It is a vivid, often dramatic, verbal description of a visual work of art, either real or imagined.
Zooming is a writing skill, as outlined in secondary education, [1] that gives the reader the feeling of moving through space towards or away from a character or object, especially used in descriptive writing. It can be divided into two types: zooming in and zooming out.
