There used to be a technical reason for 45 degree angles: as an upgrade to engineers drawing traces on big blown up transparencies to be shrunk and applied with photochemical processes... the first computer circuit CAD programs weren't able to handle more than traces with the 8 45 degree angles around a circle.
That got to be the style and (almost) nobody changed since then.
