Practical Geometry Problems: The Case of the Ritzville Pyramids

Abstract

The wheat-producing country of eastern Washington state furnishes a practical example of an applied geometry problem requiring only a knowledge of the relationship between the parts of a circle and the parts of a right triangle. The solution of this problem is related to several topics in the Curriculum and Evaluation Standards (NCTM 1989) that do not appear in a traditional curriculum. One of the main features of this example is that it shows that memorized formulas from textbooks must sometimes be modified to fit real-world problems. The solution of the problem requires the students to make some desirable connections among mathematical concepts that may otherwise be perceived as unrelated.
