Abstract

This chapter begins with a brief review of right triangle geometry, before exploring how these triangles come up in number theory. Triangles such as the two pictured below, in which one angle is a right angle, or a 90° angle, are called right triangles. Remember from geometry that the side opposite the right angle is called the hypotenuse, and the other two sides are called the legs of the right triangle.

I had this rare privilege of being able to pursue in my adult life, what had been my childhood dream.

—Andrew Wiles, 1953–present
