Pythagorean triples with rational angles? (sh.itjust.works)

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

Do you mean rational in radians, or in degrees?

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.
