From Latin irregularis, irregular It is an adjective that allows you to name what is out of order or contrary to it . The term, therefore, is opposite to regular, which is that adjusted and according to rule, uniform or that does not suffer large variations.
For example: “The tender was irregular since it was not subject to the usual controls by the supervisory bodies”, “The factory electrical connection is irregular: it does not meet 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 threatens the rights of workers ”.
Irregular is also that or that which does not always perform in the same way or that does not exhibit the same behavior . The concept also indicates to what does not ordinarily happen : “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 this is irregular, we don't usually have these inconveniences", "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. Proof of this is that all its vertices cannot be part of the same circumference, as it does, for example, with a square. One of the advantages of irregular polygons with respect to the regular ones is that for its construction the use of a compass is not necessary, but rather a rule or guide is enough to join its vertices.
There is, however, a limitation when building 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 ones, 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 infinite possibilities.
The calculation of the perimeter of an irregular polygon is very simple: you simply add the length of each of its sides. With regard to 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 are obtained, they simply proceed to find out their areas and, finally, add up to find the area of the irregular polygon of which they are part.
The grammar Finally, he argues that irregular is everything in a language , departs from the type that is considered normal. For example, irregular verbs are those that are not governed according to the conjugation model of loving, fearing and starting at the time of conjugation. In other words, the root of an irregular verb goes through modifications in its root when 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 way, since in fitFor example, there are no traces of the root AC. Other verbs that belong to this group are feeling, arriving, knowing, overcoming and understanding; Note that the variations are not always as obvious as in the case of fitting. On the other hand, there are the defects, an interesting subgroup of verbs that cannot be conjugated in all people or times; such is the case of to rain.
