Prompt: List all integer possibilites for the three sides of a right triangle where one side is 2 units shorter than one of the other sides.

Is there some algebraic method of solving this?

Also, I found a 3-4-5 triangle and a 6-8-10 triangle. Both of these triangles have the same angles, which are 90 degrees, 36.86989765 degrees, and 53,13010235 degrees. Maybe this could mean something?

Any suggestions?
