Yes you have to use the pythagorean theorm to find the length of a right triangle. But you must subtract A2 from C2 then square root the answer.

How can you find the length of a diagonal without measuring i?
If you know the length of the sides but not the diagonal, you can use the Pythagorean Theorem.
How do you find the side of a square if you know its diagonal?
Divide the length of the diagonal of a square by 1.4142 (which is the square root of 2) to find the length of a side. Similarly, to find the length of the diagonal of a square, multiply the length of a side by 1.4142.
How do you find the diagonal of a rectangle?
By the Pythagorean Theorem, the diagonal is the hypotenuse of the right triangle formed by the diagonal and the two included sides. c2 = a2 + b2 so the diagonal is the square root of the sum of the squares of the rectangle's length and width. Example : for a rectangle 4 x 3, the diagonal is sqrt(32 + 42) = sqrt (25) = 5
The area of a square garden is 128 m squared How long is the diagonal?
First, take the square root of 128 to find the side length. Use this with the Pythagorean theorem (a2 + b2 = c2) to find the length of the diagonal, which is the hypotenuse of a triangle that takes up half the area of the whole garden. The diagonal ends up being 16 m. The steps are a bit hard to write on this page, so I've included them in the "related links" section, below.
What was the pythagorean theorem used for?
The Pythagorean theorem is used to find the length of the hypotenuse of a right triangle. It states that the length of the hypotenuse is equal to the square root of the sum of the squares of the other two sides.
How do you find the diagonal of an rectangle with all right angles?
Pythagorean theorm!!
How can you find the length of a diagonal without measuring i?
If you know the length of the sides but not the diagonal, you can use the Pythagorean Theorem.
How do you count the number of squares crossed by the diagonal in a rectangle?
To find the length of a diagonal in a rectangle, use the Pythagorean method. Diagonal length = square root(length squared + height squared).
How do you use the pythagorean theorem to find the length of a diagonal of a rectangle with the side lengths of s and t?

How do you find the volume of a cubical box when diagonal is given?
Cool question ! Answer - half it then cube it to prove it - an example for you if cube diagonal (not square diagonal) is 100, then using pythagoras theorm the square diagonal = 70.71068, If square the square diagonal = 70.71068, then using pythagoras theorm the side length = 50 therefore the volume = 50 ^ 3 = 25000 units works with any numbers
The diagonal of a rectangle is 15cm find the length of the longest side which has a shorter side of 9cm?

How long is the diagonal of a rectangle with dimensions 7in by 10in?
You use the pythagorous theorm to calculate the hypotenuse of the triangle, which is the same line as the diagonal. 7(7)+ 10(10)= diagonal x diagonal 149= diagonal x diagonal Diagonal= square root of 149: this approximates to 12.207in Visit quickanswerz.com for more math help/tutoring! Consider a rectangle with dimensions 7 inches by 10 inches. Let ABCD be the rectangle. We need to find the length of the diagonal. We know that the diagonals of a rectangle are same in length. So, it is enough to find the length of the diagonal BD. From the rectangle ABCD, it is clear that the triangle BCD is a right angled triangle. So, we can find the length of the diagonal using the Pythagorean Theorem. BD2 = BC2 + DC2 BD2 = 102 + 72 BD2 = 100 + 49 BD2 = 149 BD = √149 BD = 12.207 So, the length of the diagonal is 12.21 inches.

How do you use a Pythagorean theorem with cube?
You can use pythagorean theorem twice to find the diagonal of a cube
How can I find the square foot of a roof pitch?
The great pythagorean theorm: a(squared) + b(squared) = c(squared)
If you use the Pythagorean theorem to find the length of a diagonal in a square and all sides are 25m would the answer be 1250m?
Doesn't seem likely, does it? A diagonal 50 times the length of the sides? Diagonal = sqrt(252 + 252), ie sqrt 1250(!) which is 35.36 to the nearest hundredth.
If the volume of a cube is 125 find the length of one of the face diagonals of the cube?
find the cube root of 125(which is 5) is the length of one side do Pythagorean theorem to find the diagonal 5squared plus 5 squared=50 square root of 50=7.07106781 is diagonal
How do you find the diameter of a square?
Squares do not have diameters; circles have them. If you are referring to the diagonal of a square, then you would use Pythagorean's Theorem to determine the length of the diagonal. 'Square' the length of one side and multiply by 2, then take the square root of that number to get the length of the diagonal. that is = under root( 2 s) where s= side
