Which is closer to the post office? (b)Now nd the following distances in both Euclidean and taxicab geometries. Check your student’s understanding: Hold a pen of length 5 inches vertically, so it extends from (0,0) to (0,5). The roads are on a grid system and the students can "travel" different routes of the same distance to reach the same destination. <> This is used for city planning. <> Like Alice and Bob, he walks to work along the city blocks.

If you deviate from this segment in any way in getting from one point to the other, your path will get longer. Distance is not measured as the crow flies, but as a taxicab travels the "grid" of the city street, from block to block, vertically and horizontally, until the destination is reached.

They then use the definition of radius to draw a taxicab circle and make comparisons between a circle in Euclidean geometry and a circle in taxicab geometry. 2 0 obj Group activities in Taxicab Geometry included explorations of • Taxicab Distance; Math 361 ACTIVITY 2: Some work with the taxicab distance Why The taxicab plane (Cartesian plane with the taxicab metric) provides a useful comparison to the Euclidean plane for checking what our axioms do (or don’t) say. Then the distance from P to l is the minimum TC distance PQ where Q is a point on l. Discussion: Three cases are presented. Note that he … Jul 13, 2016 - Worksheets allow students to explore taxicab geometry using hands-on measurement and a map of an actual area in Texas. Do you have wings? Movement is similar to driving on streets and avenues that are perpendicularly oriented. The shortest distance from the origin to the point (1,1) is now 2 rather than. On a graph, shade in all the places Doug can live. endobj Taxicab geometry is a geometry with a grid, so think of drawing all your shapes and lines on graph paper (2). Because of this, we believe that students should be able to see, learn about, and investigate different topics within Taxicab Geometry. Taxicab geometry is a form of geometry, where the distance between two points A and B is not the length of the line segment AB as in the Euclidean geometry, but the sum of the absolute differences of their coordinates. As a result, a model of schema interaction and suggested pedagogical activities were developed to help facilitate student understanding of the definition of a circle and other relevant concepts. So the taxicab … Taxicab Geometry Dr. Michael Scott From the presentation given at the 2004 KATM annual conference.

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. This helps us improve the way TI sites work (for example, by making it easier for you to find information on the site). 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.
