The terms plumb, square, and level are all related to geometric concepts used in construction and engineering. Plumb refers to the vertical alignment of a structure, ensuring it is perpendicular to the ground. Square involves ensuring that angles are precisely 90 degrees, creating geometrically sound shapes. Level refers to the horizontal alignment of a structure, ensuring it is parallel to the ground. These concepts are fundamental in ensuring the stability and accuracy of architectural and engineering projects.

ReneWell, darling, plumb, square, and level are all terms used in construction and carpentry to ensure things are straight and true. Plumb refers to something being perfectly vertical, square means perfectly at right angles, and level is all about being perfectly horizontal. So, in a nutshell, these terms are all about keeping things in line and looking sharp, just like me!
A plumb is a line which tells whether something is vertical. It used to be a string with a lead weight called a plumb bob (from the Latin word plombium, meaning lead) which could be held against vertical structures like walls to test them. A level tests whether a horizontal structure like a floor is perfectly horizontal. Carpenter's levels nowadays use bubbles in clear vials to show when the surface the level is placed on is horizontal. A square is something to measure whether the angle of two things (such as a wall and a floor) is ninety degrees. The connection of the square with geometry is obvious. Whether the corner of a quadrilateral is ninety degrees is important to the definition of a square and a rectangle. Also, if one of the angles of a triangle is ninety degrees, all of the principles of trigonometry apply to that triangle. The plumb and level describe relationships in three-dimensional geometry. Since the earth is (approximately) a sphere, and the plumb bob is pulled by gravity to the centre of the earth, the line described by the plumb is the extension of a radius of the terrestrial sphere. Likewise the level tests lines to see if they are tangent to a point on the surface of the terrestrial sphere or a parallel to that one. A plane which is level contains such a line and is therefore tangent to a point on the surface or parallel to such a plane. A plane which is plumb contains a line which is plumb; the level and plumb planes meet at a ninety degree angle and the line where they intersect is tangent to the surface, or parallel to a tangent.

Can something be level and out of plumb?
YES. Level is interpruted to be horizontal and plumb vertical. Now, most levels have a plumb level and can be used in the vertical position. this is stil however checking for plumb and not level. Hope this helps Terry
How are plumb line spirit level and try square related to perpendicular lines?
EWANImproved Answer:-They are both used to mark out right angles which are perpendicular lines that intersect each other at 90 degrees.
What is a plumb line?
A plumb line is a weighted string which when hung from a fixed point and allowed to become motionless, indicates perpendicular to level. Perfect for aligning vertically that first piece of wallpaper.
What are measuring tools?
AnswerAnswerThis really can include lots of tools. Things such as tape measure, ruler, plumb bob, level, Line level, and speed square. Levels are really measuring devices, but it is impossible to build a deck or something of that sort without one. Good luck.
Who invented the plumb line?
It is not known who invented the plumb-line or plumb-bob; there is evidence that it has been in use since biblical times and archaeologists haveÊunearthed what they think are plumb gaugingÊtoolsÊin Ancient Egypt.
