Surds may be used to calculate diagonals of squares or rectangles or equivalently, the hypotenuses of right angled triangles.
While this may seem a pointless exercise, consider the following: if you have a dorrway that is 2 m high and 1 m wide, can you get a 2.2 m wide sheet through it without bending it? Of course, it won't go through straight up but what if you tilt it? What is the longest stick you can fit in a box whose dimensions are known?

How do you find surds?
Surds are normally irrational numbers.
Are surds plant roots?
No. Surds are a part of maths, and are the opposite of powers.
What is the difference between surds and irrationals?
Roots that are irrational are called surds. There are irrational numbers that are not surds since they are not roots of any equation. For example, Pi. Rational roots, such as square root of 4, are not surds.
Who created surds?
Princewilly created surds. he has a bold head. his nickname is britney this was posted by, Elena Whiteman
What are like surds?
the limit does not exist
What is surds in algebra?
Irrational numbers
Who created maths surds?
Whoever it was who discovered that if you had a square whose sides were one unit long, the lengths of its diagonals were sqrt(2) - surds!
Can a surd be negative?
No, surds can never be negative.
Why are irrational numbers called surds?
Irrational number are NOT called surds. For example, pi is irrational but it is not a surd.Surds are a very small subset of irrational numbers.
How do you work out surds?
Surds are normally irrational numbers but they can be simplified for instance the square root of 12 can be expressed as 2 times the square root of 3
How do you understand Surd's in maths?
How one understands surds depends on the person. If you would like to know what surds are, or have help understanding surds A surd is an unresolved radical, meaning that it is a root with the radical sign still on it. It is easier (and more accurate) to express it this way than writing it out for many numbers if the root is irrational. The concept of irrational numbers (which is what surds are, usually) can be confusing. In short, they are numbers that are not rational, that is, they cannot be written as a fraction. When using surds in math, you treat them just as you would a written out number.
Why are surds useful in math?
They define irrational numbers
