Once you split a square down the diagonal you now have 2 right triangles. Use Pythagorean's theorem to figure the side length.
a² + b² = c²
Since this is a square, a = b, so you can subtitute x for both sides
2x² = 8² (remember c is the hypotnuse, or the longest leg of a right triangle)
2x² = 64
x² = 32
x = √32
x ≈ 5.657 feet or 4√2 leaving your answer as a radical

What is a diagonal vertex of a square?
The diagonals of a square bisect each corner or vertex of the square.
Diagonal of a square?
A square has 2 diagonals that are equal in length and bisect each other at right angles.
What quadrilaterals have diagonal that bisect each other?
A parallelogram a rectangle a square and a rhombus
The length of a diagonal of a square is 8 cm What is the length of each side of the square?
About 5.656854249 cm using Pythagoras' theorem: 2x2 = 64
He order square-shaped floppy diskettes measured 5 in on each side what was the diagonal length of a diskette?
t he older square-shaped floppy diskettes measured 15 cm on each side. What was the diagonal length of a diskette?
How do you find the length of each side of a square?
If you are given the area of the square, then the length of each side is the square root of the area. If you are given the length of the diagonal of a square, then the lenght of each side is equal to the length of the diagonal divided by the square root of 2. l=sqrt(a) l=d/[sqrt(2)] l=length of side, d=diagonal, a=area, sqrt means square root
If perimeter of a square table is 12 feet What is the lenght of each side of the table?
In a square, all four sides are of equal length. Divide the perimeter by four to find the length of each side: 12 ÷ 4 = 3 ft
What is the length of each diagonal of a square that is 45 cm on each side?
The diagonal is 63.64 cm
When you know the sum of lengths of diagonal of a square how to find each diagonal?
To find the length of each diagonal of a square, divide the sum of the diagonal lengths by 2. Since a square has two diagonals of equal length, this division will give you the length of each diagonal.
What is a diagonal vertex of a square?
The diagonals of a square bisect each corner or vertex of the square.
How long is the diagonal of a square if each side is 12 inches long?
The diagonal is about 16.97 inches long.
The perimeter of a square is 100 feet and the area is 625 square feet what is the lenght of each side?
25 feet
How do you find out the length of a diagonal in a square?
Use Pythagoras. The diagonal, and two sides of the square form a right angled triangle. So if each side of the square is x cm long, the diagonal is x*sqrt(2) cm long.
Diagonal of a square whose area is 36?
The diagonal of a square whose area is 36 is the square root of 72, or about 8.49. Since the area of a square is side(squared), then the sides are each 6. Then since a(squared) + b(squared) = c(squared), for a triangle (the diagonal), you get the square root of 72.
Diagonal of a square?
A square has 2 diagonals that are equal in length and bisect each other at right angles.
The length of the diagonal of a square is 22 feet what is the length of each side of the square?
15.556 feet (rounded)
Do the diagonals of a rhombus bisect its opposite angles?
Yes. In a rhombus (and in a square), the opposite angles that each diagonal connects are bisected by the diagonal.
