Eggleton’s article featured in the Mathematics Teacher

“Triangles a la Fettuccini” proves great exercise for math students
Huntington, Ind.—Huntington College Associate Professor of Mathematics, Dr. Patrick Eggleton, has an article that is featured in the October 2001 issue of the Mathematics Teacher. The article regards the instructional activity, “Triangles a la Fettuccini: A Hands-on Approach to Triangle-Congruence Theorems.” Included are pictures taken by Huntington College student Summer Zimmer and quotes from the Huntington North High School students. The cover picture of the issue, taken by Zimmer, was of the Huntington North students working on the exercise.

In May 2000, Mr. Jason Phillip’s geometry classes welcomed Dr. Eggleton to share a new instructional technique for teaching about triangle congruence. The instructional activity allows students to explore various ways of measuring two different triangles to determine if the triangles are exactly the same (congruent). Students used fettuccini noodles to create the different triangles to measure, thus providing the stimulus for Eggleton’s article, “Triangles a la Fettuccini.”

Traditionally, geometry teachers share the various theorems associated with the congruence of triangles and then assign exercises for students to apply the theorems. In Eggleston’s activity, the students develop personal rationales for the theorems by testing the many alternatives and choosing only those that prove to work.

Ashley Keller, a student at Huntington North High School, is quoted in the article, saying, “Using the fettuccini to create congruent triangles helps you see the congruence; therefore, it helps you to understand and remember the ways to prove triangles congruent.”

The Mathematics Journal is one of the official journals of the National Council of Teachers of Mathematics (NCTM). The mission of NCTM is to provide the vision and leadership necessary to ensure a mathematics education of the highest quality for all students. The Mathematics Teacher journal is distributed to more than 46,000 mathematics teachers nationally.

Founded in 1897, Huntington College is a Christian college of the liberal arts, offering graduate and undergraduate degrees in nearly 50 academic concentrations. US News and World Report ranks the College among the best Midwestern liberal arts colleges. Huntington College has also been listed among the “201 Best Colleges for the Real World.”
