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.
If you know the length of the sides but not the diagonal, you can use the Pythagorean Theorem.
To find the length of the diagonal of a rectangle, you can use the Pythagorean theorem. In this case, the diagonal forms the hypotenuse of a right triangle with the sides being the length and width of the rectangle. So, the diagonal (d) can be calculated as d = β(4^2 + 6^2) = β(16 + 36) = β52 β 7.21 feet.
If you know the length of the side, multiply it by the square root of 2.
Using Pythagoras: 322+362 = 2320 and the square root of this is the length of the 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.
The length of the other diagonal works out as 12cm
You need to use trigonometry cosine (angle) = length/diagonal diagonal = length/cos(angle)
The diagonal is 3.61cm
If you know the length of the sides but not the diagonal, you can use the Pythagorean Theorem.
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.
To find the length of a diagonal in a rectangle, use the Pythagorean method. Diagonal length = square root(length squared + height squared).
The length of the diagonal which is to opposite of 100⁰ angle is: diagonal length = √[152 + 82 - 2(15)(8)cos 100⁰] diagonal length ≈ 18 The length of the diagonal which is to opposite of 100⁰ angle is: diagonal length =√[152 + 82 - 2(15)(8)cos 80⁰] diagonal length ≈ 16
If they are the dimensions of a rectangle then use Pythagoras' theorem to find the length of the diagonal.
You square the width and subtract it from the diagonal squared. Then find the square root of this number, this number is now the length.
Use Pythagoras' theorem to find the length of the diagonal in the square
