'Angle' in the Bible

Every base had four wheels of brass, turning on brass rods, and their four angles had angle-plates under them; the angle-plates under the base were of metal, and there were ornaments at the side of every one.

The mouth of it inside the angle-plate was one cubit across; it was round like a pillar, a cubit and a half across; it had designs cut on it; the sides were square, not round.

And there were four angle-plates at the four angles of every base, forming part of the structure of the base.
