In geometry, a polygon is known as a parallelogram , which is made up of four sides and is characterized because its opposite sides are parallel to each other, this means that these sides are at equal distances. This quadrilateral is crossed by a pair of diagonals which will coincide at the same point, this being the midpoint of said diagonals. One quirk is the fact that all its consecutive angles total 180 degrees.
It is important to note that parallelograms can be of different types, on the one hand they are what are included in the group of rectangles, this is characterized by being shapes that have internal angles of 90 °, between the most prominent parallelograms of the group of the rectangles meet the squares and the rectangles. On the other hand, the non-rectangles are located, characterized by having only two acute angles and the rest obtuse, some of them are the rhomboid, and rhombus.
In order to calculate the area of a parallelogram, it is necessary to multiply the height by the base, its general formula being a = bx a. On the other hand, if what you are looking for is to know the perimeter, it is necessary that all the sides that make it up are added.
In daily life, it is possible that people often come across these figures, since there are thousands of objects that can have this shape, be it a book, a ruler, a desk, a table, among many others.
Neither parallelograms nor polygons are limited by a single science, on the contrary there are many areas in which the use of this type of figures is required, such as engineering, architecture, carpentry, drawing, design, etc.
On the other hand, there is a law called the parallelogram law, thanks to it it is possible to establish a relationship between the sides that make up the plague and its diagonals. This law establishes that when adding the squares of the lengths of the 4 sides of the parallelogram, it is proportional to the sum of the squares of the length of each diagonal.
