How Do You Spell PARALLEL RULER?

1. A parallel ruler is a tool used in technical drawing and drafting to draw parallel lines. It consists of two straight edges or rulers, typically made of transparent material, such as plastic or acrylic. These rulers are connected by a hinge that allows them to pivot, maintaining a consistent distance between the two rulers at all times.

   The parallel ruler is primarily used to create parallel lines, especially when a precise and consistent distance is required. It is commonly employed in architectural, engineering, and artistic drawing, particularly for plan drawings, isometric views, and perspective sketches.

   To utilize a parallel ruler, one ruler is held stationary while the other is moved or pivoted along the hinge. The distance between the two rulers remains the same, ensuring that any line drawn with the moving ruler remains parallel to the stationary ruler. This tool allows for efficient and accurate creation of parallel lines without the need for manual measurements or calculations.

   Parallel rulers may also include additional features, such as a protractor scale or an adjustable angle arm, to assist with other aspects of technical drawing. This versatile tool is an essential component of a drafter's toolkit, aiding in the creation of precise and consistent parallel lines and contributing to the overall quality of technical drawings.

2. A mathematical instr. formed by two equal rulers united by two cross-bars of equal length, and movable.

Common Misspellings for PARALLEL RULER

The word "parallel ruler" is a combination of two separate words, each contributing to its meaning:

1. Parallel: The term "parallel" comes from the Latin word "parallelus", which derives from the Greek "parallēlos", meaning "side by side" or "alongside". The concept of parallel lines, which never intersect and remain equidistant from each other, has existed in geometry since ancient times. The word "parallel" was first used in English around the early 16th century to describe lines or objects that maintain a constant distance from one another. In the context of a ruler, "parallel" refers to the ability to draw lines that remain consistently equidistant from each other.

2. Ruler: The term "ruler" has its roots in the Old Norse word "rægla", which means "a straight edge".
