Construct the rectangle that contains the right angle subtended by the vectors. Calculate or construct the diagonal of the rectangle. The diagonal is the hypotenuse of a right triangle with the two vectors as sides. The hypotenuse is also the vector that is the sum of the two original vectors. Calculate the magnitude of that vector by applying the theorem.

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.
What is the Pythagorem theorem used for?
The Pythagorean theorem is used to find the length of a side of a right triangle knowing the length of the other two side.
Pythagorean theorem to find the length of the side marked withy an x in the right triangle?
The Pythagorean Theorem states that a2 + b2 = c2, where c is the longest side (opposite the right angle). Replace the sides you know, and solve for the other side.
What are some common proofs for the Pythagorean theorem?
the square on the hypoteneuse is equal to the sum of the squares on the other two sides.
What squared numbers the Pythagorean Theorem?
a2 + b2 = c2 a = a leg of the triangle, b = the other leg of the triangle, and c = the hypotenuse
Are there any limitations to pythagorean theorem?
The triangle concerned MUST be a right-angle triangle. If one of the angles is not 90 degrees, you cannot use the Pythagorean theorem! Also, it must be remembered that the theorem only involves the magnitudes (lengths of the sides), you can't use it on i-j-k vectors or the like, only their magnitudes. As a result, it cannot tell us anything about the directions or angles between lines. Other than that, the Pythagorean theorem is incredibly sound!
When finding the resultant of two vectors at right triangles you should use what?
Like with all other right triangles, use the Pythagorean Theorem. If you have 2 vectors that form a right triangle, the resultant should be the hypotenuse. So you just need to square both of the vectors, add them together, then take the square root. a2+b2=c2
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 is the Pythagorean theorem used to develop the equation of a circle in standard form?
The Pythagorean theorem is used to develop the equation of the circle. This is because a triangle can be drawn with the radius and any other adjacent line in the circle.
What is the Pythagorem theorem used for?
The Pythagorean theorem is used to find the length of a side of a right triangle knowing the length of the other two side.
From which civilization did Pythagoras borrow the 'Pythagorean Theorem'?
Pythagoras did not borrow the Pythagorean Theorem from any particular civilization. The theorem, which states that in a right-angled triangle the square of the hypotenuse is equal to the sum of the squares of the other two sides, was discovered by Pythagoras himself and is named after him.
How do you use Pythagorean theorem when you only know one side of the triangle?
Since the Pythagorean theorem has 3 variables (the 3 sides), and you only know one variable, you cannot use it to solve for the other 2 variables. Do you know any other information (like angles)? that can be used to solve the triangle (you would not be using the Pythagorean theorem, though). Did they mark the 2 legs with little 'tick marks' denoting that they are equal? Then you could use the Pythagorean theorem because then you know 2 varaibles, and you can solve for the third variable.
Who began pi?
Pythagorus, remember he made other theories too like the Pythagorean Theorem.
What are the other areas of maths besides geometry that make use of the Pythagorean Theorem?
Trig., Calculus.
How do you find hypotenuse square?
Sum the squares of the other two legs of the triangle. This is the Pythagorean Theorem.
What is meaning of the pythagorean theorem?
In mathematics, the Pythagorean theorem, also known as Pythagoras's theorem, is a relation in Euclidean geometry among the three sides of a right triangle. It states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
What is phythagorean theorem?
The formula for the Pythagorean Theorem is a2+b2=c2 :] The Pythagorean Theorem is finding the measurements in a right triangle. The side of the triangle across from the right angle is called the hypotenuse and the two other sides are called the legs :3 I hope I could help! <3
