**GEOMETRY***square*is a regular

**quadrilateral**and at the same time, a

**right rectangular rhombus**. It's a

**parallelogram**, and a

**trapezoid**(or

**trapezium**in some places).

A

*square*is a

**two-dimensional**(

**planar**) object. A

**polygon**with four sides and four vertices (corners). All four sides are of equal length. All four angles are equal. All angles are 90 degrees (right angles).

A

*square*'s

**diagonals**are of identical length. They divide each other and the corner angles in half, and are perpendicular to one other. That means they are

**perpendicular bisectors**.

The diagonals are equal to the length of one side of a square multiplied by the

**square root**of 2, or 1.414 times as long (Pythagorean Theorem).

A

*square*'s

**perimeter**is 4 times the length of one side. Its

**area**is equal to the product of two adjacent sides, or one of the sides

*squared*. There is no

**volume**to a square because it's on a planar surface.

Simple, eh?

Those are most of the definitions of a

*square*. Now we have lots of other words that we can define more clearly. Later. Another time.

Like many of us, the

*square*comes from a large family. In this case, it's the family of quadrilaterals (figures made up of 4 lines or having 4 sides).

Thanks to Wikipedia, here's a picture of the SQUARE FAMILY TREE.

We haven't exhausted the meaning of the word square.

**CARPENTRY**

**ARCHITECTURE**

**SOCIETY**

*I'm going to square with you*" or "

*our accounts are squared up*" or "

*he looked him squarely in the eye*".

It means substantial and sufficient - such as "

*three square meals a day*."

A square is a term sometimes applied to a person who likes math. Someone who is not too hip or connected with modern thinking and acting. You could say they are

*"a square peg in a round hole."*

Here's a perfect Christmas gift for a square.
