Are there any known right triangles that have integer side lengths and rational angles? If not, has it been proven that none exist?

I was thinking of degrees, or fractions of a whole (2π radians), though either would be interesting. I would be quite surprised if any such triangles existed with rational angles in radians, given that π is irrational.
