Planimetric Ruler

Planimetric ruler: what is it and how to use it

A planimetric ruler is a tool used to measure distances on a plane. It consists of a straight line with divisions on it. Each division corresponds to a certain distance, which can be measured by applying a ruler to the surface.

The word "planimetric" comes from the Latin "planum" - surface, plane and the Greek "metreo" - to measure. This means that a planimetric ruler is designed to measure distances on a flat surface.

A planimetric ruler can be made of various materials, such as plastic, metal or wood. The most common rulers are made of plastic, as they are lightweight and inexpensive.

Using a planimetric ruler is very simple. It is necessary to attach it to the surface to be measured and read the scale. In this case, it is necessary to take into account the units of measurement that are used on the ruler, for example, centimeters or inches.

The planimetric ruler is widely used in various fields such as construction, architecture, engineering, surveying and design. It is used to measure the lengths of segments, the sizes of figures, distances between objects and other parameters.

In conclusion, a planimetric ruler is a simple and reliable tool for measuring distances on a plane. It has wide application in various fields and is available in various designs. If you work in an area where you need to measure distances on a plane, a planimetric ruler will be an indispensable assistant in your work.

* **What it is**

If you are a student and studied the sciences of space and geometry in your first year, then chances are that among your geometry tools will be a planimetric ruler. This is a tool for measuring and transferring the areas of figures in a drawing. How long can you live without this tool or come up with something instead? Let's look at the benefits of planimetric rulers. This is a long wooden strip with millimeter divisions. At one end there is a small ruler with divisions from 2 mm to 4 mm. The kit includes clamps for fixing the ruler in the desired position. **Basic designations of a planimetric ruler** A - length of the entire ruler B, C, D - various divisions and fastenings. Most often fixed by adjusting the moving part and screw E - moving part F - 2 mm markings G - ¼ millimeter divisions (or five hundredths) **Surface Types** There are six basic surface types in geometry. Planimeters can also work with these types of surfaces, namely
