On the beam; a relative bearing at right angles to the ship's keel; e.g. describing an object located at a bearing of 90 degrees or 270 degrees as measured clockwise from the ship's bow. [7] able seaman (AB) Also able-bodied seaman. A merchant seaman qualified to perform all routine duties on a vessel, or a junior rank in some navies.
pipe (bos'n's) Also bosun's call. A whistle used by boatswains (bosuns or bos'ns) to issue commands. Consisting of a metal tube that directs the breath over an aperture on the top of a hollow ball to produce high-pitched notes. The pitch of the notes can be changed by partly covering the aperture with the finger of the hand in which the pipe is ...
The straight lines which form right angles are called perpendicular. [8] Euclid uses right angles in definitions 11 and 12 to define acute angles (those smaller than a right angle) and obtuse angles (those greater than a right angle). [9] Two angles are called complementary if their sum is a right angle. [10]

A JIC bulkhead adapter, which converts National Pipe Thread (NPT) on the left to JIC on the right. The angled seating surface is clearly visible on the far right.
Then use the SAS congruence theorem for triangles OPA' and OPB' to conclude that angles POA and POB are equal. To make the perpendicular to the line g at or through the point P using Thales's theorem, see the animation at right. The Pythagorean theorem can be used as the basis of methods of constructing right angles. For example, by counting ...
