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)
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.
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
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
