The article presents a list of essays included in the book "What Is Geometry?," edited by Giandomenico Sica, including "About Culture and Geometrical Thought," by Paulus Gerdes and "Tubular Geometry Construction As a Reason for New Revision of the Spac...
A projected coordinate system consists of a linear unit of measure (usually meters or feet), a map projection, the specific parameters used by the map projection, and a geographic coordinate system. The following example is the string representation of the California State Plane Zone, which is...

In geometry, a horizontal line is any line that runs from left to right. A horizontal line has a slope of 0 and is parallel to the x-axis on a graph. When graphing linear equations, the horizontal line is the simplest type of line. You can see examples of horizontal lines all around...
Without the T-shaped, calibrated scale bar, it is impossible to tell how big (or small) this crankshaft is. Scale bars are calibrated, linear bars with printed markers called targets attached to them. The targets on scale bars are coded. This means software can uniquely identify each target...
is processed to produce digital elevation data and orthomosaics. Imagery has perspective geometry that results in distortions that are unique to each image. Orthoimages have been geometrically corrected so that the resulting image has the geometric integrity of a map, and orthomosaics are orthoimages...
andthe minimum ofz= −15occurs at(−1, −3). Affiliate As you can see, solving a linear-programming exercise can be a lengthly process, but each individual step is fairly straightforward. Just take your time, label clearly, and work neatly, and you'll get it!
The linear measurement is the distance between the two givenpointsorobjects. Thus, we can definelengthas: “Total gap measured between the leftmost and rightmost end of an object in the mentioned system ofunits.” Measuring the length of a banana using tape. The length approximates to 5 inche...
Uses of Straight Angle in Geometry The most obvious use of a straight angle is when measuring lines and shapes that are linear—that is, they don’t curve or bend much if at all—such as rectangles or squares. However, there are also uses for this type of angle beyond simply measuring ...
What is the zero vector in linear algebra? What is r^n, spaces, and planes in linear algebra? Find the standard matrix of the linear transformation T(x,y,z) = (x - 2y + z, y - 2z,x + 3z). Is algebraic geometry just linear algebra? What is a free variable in linear algebra?
