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.
pythagorean triplets:
3,4,5
5,12,13
8,15,17
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
pythagoras theorem
a f-cking 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
