A Square is a flat shape with

**4 equal sides**and every angle is a right angle (90°) and opposite sides are parallel.####
**Diagonals**...

A square has two diagonals, they are equal in length and intersect at the middle point.

The Diagonal is the

**side length(a)**times the square root of 2:

***side length = a = the length between A and D*** (see image at top)
Diagonal "d" = a × √2

#### Perimeter...

The Perimeter is 4 times the

**side length:**

Perimeter "p" = 4a

#### Area...

The Area is the

**side length**squared:

Area = a

^{2}= a × a
....or half of the

**diagonal**squared**:**
Area = d

^{2}/2###
What this looks like in **ICE **....

#### Side length

To work out the**side length**of the square shown below.....

..... Subtract the corner point (-1,-1,0) with corner point (-1,1,0). Then simply get the length of the vector between the them.

#### Perimeter

The light green perimeter value is worked out with the math sum shown below, while the darker green value shows the curve length attribute in**ICE**, they are both the same.

p = 4.a

#### Diagonal

The diagonal length as shown by the blue value below was got by....d = a . √2

#### Area

Area can be calculated two ways, by multiplying the side lengths or by the diagonal......... here are what those calculations look like in

**ICE**.
