Question: are pythagorean triples 30 60 90?
Answer: Because at least one side of a 30°- 60°- 90° triangle must contain a square root, a 30°- 60°- 90° triangle cannot belong to any of the Pythagorean triple triangle families. ... There's no overlap between the 30°- 60°- 90° triangle and any of the Pythagorean triple triangles and their families.
