From Latin irregularis, irregular is an adjective that allows naming what is out of rule or contrary to it. The term, therefore, is opposite to regular, which is that adjusted and in accordance with the rule, uniform or that does not undergo great variations.

For instance: “The tender was irregular since it was not subject to the usual controls by the supervisory bodies”, “The electrical connection of the factory is irregular: it does not comply with the parameters required by law”, “We need to normalize this irregular activity to avoid accidents and other problems”, “The government must persecute anyone who offers job irregular and that violates the rights of workers “.

Irregular is also that or that which does not always perform in the same way or that does not present the same behavior. The concept also makes it possible to point out to what does not happen ordinarily: “My work is irregular, I have good months and bad months”, “The team showed a performance irregular throughout the tournament, with ups and downs “, “I assure you that this is irregular, we do not usually have these problems”, “If it were not so irregular, this tennis player would be part of the Top Ten”, “I can’t understand what happened: this event was somewhat irregular”.

For the geometry, an irregular polygon (or polyhedron) is one that is not regular, that is, its sides (or faces) and angles are not equal to each other. A proof of this is that all its vertices cannot be part of the same circumference, as it happens, for example, with a square. One of the advantages of irregular polygons with respect to regular polygons is that their construction does not require the use of a compass, but rather a rule or guide is enough to join their vertices.

There is, however, a limitation When constructing an irregular polygon: it is not possible to join a point to two or more, but the connection must be one to one. The classification of irregular polygons is equivalent to that of regular polygons, since they are distinguished according to the number of sides that make them up; in this way, we find triangles, pentagons, decagons and hectagons, among the infinity of possibilities.

The calculation of the perimeter of an irregular polygon is very simple: you simply have to add the length of each of its sides. Regarding your area, it is necessary to resort to the technique known as triangulation, which consists of splitting a polygon in as many triangles as possible (it should be mentioned that quadrilaterals are also accepted); Once these figures have been obtained, we simply proceed to find out their areas and, finally, they are added to find the area of ​​the irregular polygon of which they are part.

The grammar, finally, maintains that irregular is everything that, in a tongue, deviates from the type that is considered normal. For example, irregular verbs are those that are not governed by the conjugation model of love, fear and leave when conjugating. In other words, the root of an irregular verb undergoes modifications in its root when it is conjugated, unlike what happens with the three mentioned above.

This can be clearly seen if the verb is taken as an example to fit and it is conjugated in the weather present in the indicative mood, since in fit, for example, no traces of the root remain AC. Other verbs that belong to this group are feel, arrive, know, overcome and understand; note that the variations are not always as evident as in the case of fit. On the other hand, there are the defectives, an interesting subgroup of verbs that cannot be conjugated in all persons or tenses; such is the case of to rain.
