Artlex Elements of Art: Line
as five minutes, and as short as a few seconds. Others are continuous-line and contour drawing. Examples: Mike Reed (American, contemporary), Gesture Drawing of Reclining Woman, charcoal pencil on newsprint, 18 x 11 inches, drawn while observing a model's 5 minute pose. "I am a...
Line definition (Coordinate Geometry)
the definition of a line in ordinary plane geometry, the only difference being that we know the coordinates of the points involved. The naming conventions are also the same. Things to try In the above diagram, press 'Reset'. The line AB passes through point A at (52,7), point B at...
Vertical line definition. (Coordinate Geometry)
for a vertical line the slope is undefined. As you drag the points above, notice that the slope indicator goes away when the line is exactly vertical. The equation of a vertical line is x = a Where: x is the coordinate of any point on the line ais where the ...
Horizontal line definition. (Coordinate Geometry)
Examples Fig 1. Is the line horizontal? Determine if the line shown in Fig 1 is horizontal and write it's equation. The two points A,B on the line are at (7,7) and (39,7). The second coordinate in each pair is the y-coordinate which are 7, and 7. Since they are equal, the ...
Nazca Lines
they ancient road maps or messages for visiting aliens? Lying at the foothill of Peru's Andes Mountains is the site of one of the world's greatest mysteries. Etched, as if by giants, onto its arid, moonscape plains are immense lines that stretch for miles, forming strange shapes...
Foundations in Art - Cross-Hatching
layers criss-crossing lines to create a feeling of shadow. BUT cross-hatching is also very much an attitude about drawing and understanding what you see. The lines and marks that make up cross-hatching describe planes of form and begin by following planes of form--like cross-contour lines do...
San Marcos In The Desert
straight line breaks to the dotted line where stark necessity ends and thus allows appropriate rhythm to enter in order to leave suggestion. 1932, 1931 Aerial perspective for San Marcos in the Desert This drawing appears to have been done in preparation for the more fi...
Parallel lines. (Coordinate Geometry)
are equal. The slope can be found using any method that is convenient to you: From two given points on the line. (See Slope of a line). From the equation of the line in slope-intercept form From the equation of the line in point-slope form And of course, you can use d...
Intercept (b) of a line (Coordinate Geometry)
off the top or bottom of the chart. Formula for the intercept of a line Below are two ways to find the intercept. Use either one depending on what you are given to start. Given the slope of the line and any point on the line The intercept (b) is given by where: m i...
Charles A. Dana Center: Symmetry of Design: Teacher Notes
designs possible based on the transformations . (Note: There are a finite number of combinations of transformations, but there are still an infinite number of transformations possible because translations can be of any length, rotations can have any center, with any number of degrees of turn, and r...

designs possible based on the transformations . (Note: There are a finite number of combinations of transformations, but there are still an infinite number of transformations possible because translations can be of any length, rotations can have any center, with any number of degrees of turn, and reflections can use any line as a reflector.) For each rigid motion: 1. Review the rigid motions described in the notes for each section; each definition is followed by an example in the student notes. These examples
