Worksheet: Applications of Taxicab geometry Worksheet: Further Investigations Taxicab Geometry : You have to go along the lines instead of through the squares. Because of this, we believe that students should be able to see, learn about, and investigate different topics within Taxicab Geometry. Includes measurement and unit conversion. The consequences of using taxicab distance rather than euclidean distance are surprisingly varied in light of the fact that at the axiomatic level the two geometries differ only in that euclidean geometry obeys S-A-S (side angle side) as a congruence axiom for triangles and the taxicab geometry does not.

In taxicab geometry, the shortest distance between two points is not a straight line. In this geometry lesson plan, 10th graders investigate “taxicab geometry.” Students investigate the taxicab distance formula and make comparisons between a circle in Euclidean geometry and a circle in taxicab geometry. 26/mai/2017 - A few weeks ago, I led a workshop on taxicab geometry at the San Jose and Palo Alto Math Teacher Circles. This Taxicab Geometry-ID: 8643 Lesson Plan is suitable for 10th Grade. Taxicab Geometry Dr. Michael Scott From the presentation given at the 2004 KATM annual conference. You'll go roughly 8 blocks east and 9 blocks north, for a total distance of 17 blocks (I realize not every block is the same length in Manhattan, but let's not worry about those details here -- as they say in the local language, 'fuggedaboutit'!). This idea of counting distance only in the north-south (or vertical) a… ; Use the arrowhead tool to select the point on the left and under Transform, release on Translate.Change the angle to 0 degrees. The movement runs North/South (vertically) or East/West (horizontally) ! The roads are on a grid system and the students can "travel" different routes of the same distance to reach the same destination.

A nice bonus was that this article appears in an NCTM publication, thus providing immediate reassurance that our use of non-Euclidean geometry is in fact relevant to the K–12 classroom. Creating a Taxicab Script to Measure Taxicab Distance; Open up Sketchpad and use the point tool to create two points that are not on the same vertical or horizontal line. You Now tilt it so the tip is at (3,4). This study aimed on the process of teaching taxicab geometry, a non-Euclidean geometry that is easy to understand and similar to Euclidean geometry with its axiomatic structure.
