    Yes. They’re n, n times the square root of 3, 2n.

      A 30-60-90 degree triangle is half of an isosceles triangle. The shortest side must be half the longest side.

        Isosceles or scalene?

          Sorry. I meant equilateral. 🙁

          Cut me some slack. I left school in 1965, it’s been a long time since I needed to know this stuff. 😉

            You’ve done well. I left school later than that and so defer to my elders. 🙂

        Correct, and 3rd side is sqroot(2), i.e. 1.414 longer than the shortest side
