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. Taxicab geometry, as its name might imply, is essentially the study of an ideal city with all roads running horizontal or vertical. The crux is that you cannot go through the squares on the grid diagonally. In Euclidean geometry, the shortest distance between two points is a straight line segment. The Museum or City Hall? In this regard, several teaching activities were designed such as measuring taxicab distance, defining a taxicab circle, finding a geometric locus in taxicab geometry, and real life problems. 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. If you deviate from this segment in any way in getting from one point to the other, your path will get longer. D (a)Graph the points A= (1;3), B= (1; 2), C= ( 3; 1), and D= (0;3). Shortest paths in Taxicab Geometry A cab driver in New York picks up a passenger at Madison Square Garden and asks to travel to a theater which is four blocks north and two blocks east. <>stream Check your student’s understanding: Hold a pen of length 5 inches vertically, so it extends from (0,0) to (0,5). In this regard, several teaching activities were designed such as measuring taxicab distance, defining a taxicab circle, finding a geometric locus in taxicab geometry, and real life problems. Give a decimal approximation to 2 decimal places. If you would like to have a go at completing a worksheet on Taxicab Geometry, one can be found here. In taxicab geometry, there is usually no shortest path. 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.

Taxicab Geometry Worksheet Math 105, Spring 2010 Page 1 Taxicab Geometry Worksheets Exploring Mathematics, Spring 2010 Day 1: Taxicab Distances 1. Taxicab Geometry Dr. Michael Scott From the presentation given at the 2004 KATM annual conference. Further, they demonstrated a variety of levels of schema interaction of their evoked Euclidean geometry schema and Taxicab geometry schema. First of all, we need to recognize that distance from a point to a line in Taxicab Geometry has the following definition: Definition: Let l be a line and P a point. Taxicab Geometry is a very unique non-euclidean geometry, in the sense that it's fairly easy to understand if you have a basic knowledge of Euclidean Geometry. One of the wonderful things about Taxicab geometry is that you can keep on investigating all manner of shapes and geometrical properties. Includes measurement and unit conversion.

This book is design to introduce Taxicab geometry to a high school class.This book has a series of 8 mini lessons. 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'!). 1 0 obj "�ǯy�ݜ�F��v#'�׮�E���+�%ƛ*����yF�#�2)n=]��?��` ��bIVO����A_,*P���雹�h1��Uۆ0'��D��΋�q���� �G�s S��� Rd�k� B��&�N�g�A��@�+'��H�.

First, some activities related to Euclidean geometry and Taxicab geometry were designed based on concept development and real-life applications, and they were administered to a ninth-grade student. 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.
