  2. Piping and plumbing fitting - Wikipedia

    en.wikipedia.org/wiki/Piping_and_plumbing_fitting

    In plumbing, the term "45-degree elbow" for example, refers to the angle of bend from the original straight pipe position (0 degrees) to the new position (45 degrees), not the actual angle formed by the joint. On a protractor, the actual angle of the above joint is 135 degrees, an obtuse angle.

  3. Angle bracket (fastener) - Wikipedia

    en.wikipedia.org/wiki/Angle_bracket_(fastener)

    An angle bracket or angle brace or angle cleat is an L-shaped fastener used to join two parts generally at a 90-degree angle. It is typically made of metal but it can also be made of wood or plastic. Angle brackets feature holes in them for screws. A typical example use of is a shelf bracket for mounting a shelf on a wall. In general, angle ...

    en.wikipedia.org/wiki/Street_elbow

    Street elbows are available with bend angles of 90°, 45°, and 22.5°. They can be used in many plumbing applications, including water supply, drainage, sewers, vents, central vacuum systems, compressed air and gas lines, heating and air conditioning, sump pump drains, and other locations where plumbing fittings would be used to join sections of pipe.

  6. Set square - Wikipedia

    en.wikipedia.org/wiki/Set_square

    These set squares come in two usual forms, both right triangles: one with 90-45-45 degree angles, the other with 30-60-90 degree angles. Combining the two forms by placing the hypotenuses together will also yield 15° and 75° angles. They are often purchased in packs with protractors and compasses.

  7. Pressure angle - Wikipedia

    en.wikipedia.org/wiki/Pressure_angle

    Pressure angles. Pressure angle in relation to gear teeth, also known as the angle of obliquity, [1] is the angle between the tooth face and the gear wheel tangent. It is more precisely the angle at a pitch point between the line of pressure (which is normal to the tooth surface) and the plane tangent to the pitch surface.
