We used existing materials such as [3] to introduce Taxicab Geometry. We may also share this information with third parties for these purposes. 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. 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. Further, they demonstrated a variety of levels of schema interaction of their evoked Euclidean geometry schema and Taxicab geometry schema. Like Alice and Bob, he walks to work along the city blocks.

Taxicab Geometry ! Because of this, we believe that students should be able to see, learn about, and investigate different topics within Taxicab Geometry. 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. This is used for city planning. 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. 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. ; Use the arrowhead tool to select the point on the left and under Transform, release on Translate.Change the angle to 0 degrees.

Taxicab geometry is based on redefining distance between two points, with the assumption you can only move horizontally and vertically. Activity Overview In this activity, students begin a study of taxicab geometry by discovering the taxicab distance formula. 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.

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. 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.
