**• What is a Square?**

A square is a four sided object or figure which has four equal sides. All corners of a square have exactly 90° and its opposite sides are parallel. Squares are often used in mathematics especially in Geometry. According to different dictionaries, a square is pronounced as skwer. The definition of square also fits accordingly for rectangle (all angles have 90°) and rhombus (all sides have equal length).

**• Square’s Diagonal**

A square has two diagonals inside they are always equal in length and intersects in the middle of the square. To compute for the diagonal’s length, multiply square root of two to the length of one side of the squares.

**• Square is Rectangle**

A rectangle should be a quadrilateral (four sided shape) with four right angles on each corner; opposite sides are equal and parallel; and whose diagonals intersect with each other. The characteristics of a rectangle also meet those of a square, thus making the square also a rectangle.

**• Square Number (n2)**

To square a number, multiply the number by itself; the product shall be called the square number. Multiplying two by two will equal to four, thus making four the square number of two.

**• Square Root (√)**

Square root is the opposite of square number and has the symbol of √. It is the base number rather than the result. Computing for square root is like thinking for a number that when it is multiplied on itself would result to the given number. The square root of 4 is 2, thus if 2 is multiplied by 2 you will get 4.

**• Solving the Volume of a Square (s2)**

The volume of a square is like computing for its area. If one side of a square has 2 inches, multiply it to 2 inches and will get 4 inches. The volume is 4 inches.

**• Solving the Perimeter of a Square (s*4)**

Perimeter is the result if you add all of the lengths of all sides of any polygon or shape. Computing for the perimeter of a square is as simple as adding up the length of all of square’s sides together.

**• Solving the Square of Binomial (x+y)2**

A binomial involves two different terms or numbers. To solve the square of binomial, first is to square the first term, next is to double the product of the first and the last term, and last is to square the last term; put it all together and the answer would be the square of binomial.

**• Solving the Square of Trinomial (x+y+z)2**

A trinomial has three different terms or numbers. To solve the square of trinomial, first is to square the first, second and third terms, then multiply the first term to the second term, the first term to the third term, and the second to the third term; put it all together to finalize the answer. The last step is also called the FOIL method.

**• Solving the Area of a Square (s2)**

A square has its own area and getting it is very simple. To solve for the area, first is to know the length of any of the sides of the square which is often being given in mathematical problems; next is to multiply the number on itself and you will get the area of the square. If there is no given length for any sides of the square you can also solve for the area by taking the diagonal length, multiply the number by itself then divide it by half and you will get the same result.
