TELL US…in your own words

Seneca students,

I need you to help us make Seneca even better.

  During the week of April 5-9, you’ll have a chance to tell us how we are doing in the services and activities outside of your classroom. For more information, a video is online at

Take part in Seneca’s version of Speaker’s Corner or get interviewed as we’ll have members of our team at your campus approaching you for your opinions.

Have your say – in your own words – and make every student’s time at Seneca a great experience.

  Thank you,

David Agnew
President, Seneca College

Pythagorean Theorem: Part 1

Professor R. Smullyan in his book 5000 B.C. and Other Philosophical Fantasies tells of an experiment he ran in one of his geometry classes. He drew a right triangle on the board with squares on the hypotenuse and legs and observed the fact the the square on the hypotenuse had a larger area than either of the other two squares. Then he asked, "Suppose these three squares were made of beaten gold, and you were offered either the one large square or the two small squares. Which would you choose?" Interestingly enough, about half the class opted for the one large square and half for the two small squares. Both groups were equally amazed when told that it would make no difference.

The Pythagorean (or Pythagoras'Theorem is the statement that the sum of (the areas of) the two small squares equals (the area of) the big one.

In algebraic terms, a² + b² = c² where c is the hypotenuse while a and b are the legs of the triangle.

The theorem is of fundamental importance in Euclidean Geometry where it serves as a basis for the definition of distance between two points. It's so basic and well known that, I believe, anyone who took geometry classes in high school couldn't fail to remember it long after other math notions got thoroughly forgotten.

Below is a collection of 82 approaches to proving the theorem. Many of the proofs are accompanied by interactive Java illustrations.
