Pythagoras' Theorem

An often used and renowned theorem by Pythagoras in the field of geometry and mathematics. It states that in a right-angled triangle, the square of the length of the hypotenuse (the longest side of the triangle and also the side opposite the right angle) is equal to the sum of the squares of the other two sides.

It is commonly written as a^2+b^2=c^2, where c denotes the length of the hypotenuse, and a and b denote the lengths of the other two sides.
Pythagoras' Theorem is often used to calculate the length of any one side of a right-angled triangle when given the lengths of the other two sides.

pythagoras theorem

Using Pythagoras Theorem, the third side of a right-angled triangle can be calculated when two sides are given.

Suppose A = length of hypotenuse and
B & C = lengths of the sides containing the right angle

Then (A^2) = (B^2)+(C^2)

Proof:

If a = angle opposite side A ( =90 degrees)

b = angle opposite side B

c = angle opposite side C

then B = A sin a and C = A cos a

Squaring and adding,we get the result.

pythagoras theorem

Simply put, in a triangle, the square of the hypoteneuse is equal to the sum of the squares of the other two sides. Simple as that.
the pythagorean theorem, in a simple mathematical formula, is: a² = b² + c²

where a is the hypoteneuse and b & c are the other two sides

A fucking useless maths thing that u will never need to use.
i can't believe we have a test on pythagoras theorem. its not like we will ever use it later on in life

Pythagorean Theorem

The only geometric theorem that will be used in the real world, primarily by tall people figuring out the best way to sleep in short people beds and TV manufacturers trying to find the largest possible number to put on the box.
Student 1: The pythagorean theorem is actually useful!
Student 2: Really? What's the pissgoreporn theorem?
Student 1: I don't fucking know!

Pythagorean Theorem

The Pythagorean Theorem states that if Pedestrian A attempts to cross in front of car B at anything less than a 90 degree perpendicular angle, we can conclude that Pedestrian A is getting cut off.
"John (the model citizen) used the Pythagorean Theorem to determine it was faster to cross the road in a straight line, rather than diagonally."

Pythagorean Theorem

1. In geometry, a theorem stating that in a right triangle, the square of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides (legs). If the hypotenuse is c units long and the lengths of the legs are a and b, then c2 = a2 + b2. The theorem provides a way of calculating the length of any side of a right triangle if the lengths of the other to sides are known.

2. Something the Scarecrow from The Wizard of Oz was unable to correctly state even after he received his brains from the wizard.
-The Pythagorean Theorem? Who needs it? Some smart little preppy kid who's gonna save the world someday?
-Actually you need it to pass this geometry test asshole! If you don't pass this you stay back another year!
