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 Segment definition (Coordinate Geometry)
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 segment AB starts at point A at (52,7) and ends at point B at (53,20). Drag A, B...
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...
Geotimes: Earth Scientists National Security
Christina Reed, Geotimes. Back in his office, Guth demonstrates this technology with a map of Hanging Rock Canyon, Calif. The contours of the canyon’s terrain are highlighted as slopes in gray and black. “It starts with digital elevation data,” he explains. “This da...
Introduction to the Elements of Design: Point and
is continuity-- this describes the tendency to "connect the dots" and so accept separate parts or points as part of a contour or form. It is hard to resist, for example, the compulsion to see two dots as implying a line, or three as framing a triangle.Similarity descri...
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...
