Let's call a solution of (1) in integers an Almost Pythagorean Triple (APT). In analytic geometry (1) represents a hyperboloid of revolution of one sheet, a doubly ruled surface. The tangent plane at a point cuts this surface in two straight lines called rulings.

The Mathematics Teacher, 1959
An ancient problem continues to fascinate and challenge. High school students know about 3, 4, 5 right triangles. Do they know about 8, 15, 17 right triangles and 861, 620, 1061 right triangles?

Digits reversed Pythagorean triples
International Journal of Mathematical Education in Science and Technology, 1998A Pythagorean triple is called digits reversed if one integer in the triple has the same digits but in an inverse order with another. Some properties and many new examples of such triples are obtained. These results present a typical elementary example showing that new flowers are growing on the old mathematical land.

Abstract The subject of this class is called number theory, which deals with the whole numbers, that is 1, 2, 3, 4 and so on and their negatives ‒1, ‒2, ‒3, …We shall not be interested in fractions or decimal numbers. This is a very old and beautiful subject but it is rather different from the way we do ordinary calculations for we ...

Nearly Isosceles Pythagorean Triples
The Mathematics Teacher, 1983With the high school mathematics curriculum as full as it is, why should we busy teachers take class time away from the syllabus to investigate patterns of no discernible practical value? My answer is that students should be made aware that there is more to mathematics than learning how to solve an endless variety of problems.
