Eric Pandiscio 

August 2004, Volume 98, Issue 1, Page 16

Abstract:
The proportional nature of geometric work, and the ways in which proportional reasoning can be employed as a generalized problem-solving tool. A geometric construction is presented for students to solve. The author gives reasoning via proof and proportions and provides extension activities.
