A square is a geometric figure that has four parallel and equal sides.
The first step we are going to take is to determine the etymological origin of the word square that concerns us now. Thus, we can establish that it emanates from the Latin term “quadratus” which means “square” and that it is made up of the following parts:
• The word “quadrum”, which can be translated as “four”.
• The suffix “-ado”, which is used to indicate that someone has received the action.
Square is a word that is usually used to name the geometric figure that is made up of four equal and parallel sides.
What is a square
A square, in this sense, is part of the set of quadrilaterals (it has four sides) and parallelograms (since these four sides are parallel). Another peculiarity of a square is that its four interior angles are right (that is, they measure 90º). For example: “The teacher asked us to draw a square whose sides measure eight centimeters” , “Juan has problems differentiating between squares, rectangles and rhombuses” , “How can I draw a square inside a circle?” .
It is interesting that we also highlight the existence of what has been called the magic square . It is a table made up of integers, which are distributed throughout it in such a way that the sum of the rows, columns and diagonals is always the same. That is, the magical norm is met.
Squares can be classified as quadrilaterals and parallelograms.
A surface measurement
The notion of square is also used to define a type of surface measurement .
When the term is added to the measurement , therefore, it is referring to the fact that it will have the same surface area as a square whose sides have said length. In this way we can talk about square kilometers , square meters , etc.
The square root
The square root of a certain number, on the other hand, is obtained by multiplying another value by itself and obtaining the first number in question as a result.
The square root of 16 , therefore, is equal to 4 , since multiplying 4 by itself ( 4 x 4 ), the result is 16 .
Other uses of the term
Likewise, we must not forget that square is also a term used to refer to a type of mold or die that is used to mint both medals and coins.
In the field of music, it is said that a square is a note that has the value of two major measures.
In colloquial language, meanwhile, square can be an adjective used to describe someone who is stubborn or brutish : “You can't be so square! It is dangerous to connect an appliance with wet hands.”
Square as a last name
In addition to all the above, we have to say that the word in question is the one that gives shape to the surname of a famous Colombian soccer player. This is Juan Cuadrado, who plays both as a midfielder and as a right back.
He has been international on several occasions with his country's national team and is currently part of the ranks of the Juventus team. He previously played for Udinese and US Lecce, among other teams.
