Taxicab geometry, as its name might imply, is essentially the study of an ideal city with all roads running horizontal or vertical. So the taxicab … In taxicab geometry, there is usually no shortest path. This idea of counting distance only in the north-south (or vertical) a… Get this from a library! If not, then you'll have to jump in a taxi and follow the grid pattern of streets. Activity Overview In this activity, students begin a study of taxicab geometry by discovering the taxicab distance formula. Taxicab Geometry Dr. Michael Scott From the presentation given at the 2004 KATM annual conference. 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. He is forced to follow the roads, which are laid out on a grid.

The study was carried out in two stages. Tenth graders explore non-Euclidean geometry. The roads must be used to get from point A to point B; thus, the normal Euclidean distance function in the plane needs to be modified. Note that he … Group activities in Taxicab Geometry included explorations of • Taxicab Distance; Movement is similar to driving on streets and avenues that are perpendicularly oriented. The roads are on a grid system and the students can "travel" different routes of the same distance to reach the same destination. In Euclidean geometry, the shortest distance between two points is a straight line segment. All rights reserved.

Do you have wings? 1 0 obj 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. (a)Graph the points A= (1;3), B= (1; 2), C= ( 3; 1), and D= (0;3).

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. Check your student’s understanding: Hold a pen of length 5 inches vertically, so it extends from (0,0) to (0,5). Download free 90-day trial versions of the most popular TI software and handheld emulators. You have to go along the lines instead of through the squares.
