Question

prove that the pythagoras theorem.......plz..

Answer 1

Well there are lots of proof of it you can find on internet but I remember this one:

Construct A ΔABC with AB=a; BC=b; CA=c

Now make a square with side c and make the other side too (a and b) with each side of square.

Angle opposite to a and be sum up to 90° and angle in a square is also 90° so the a and b side of the adjacent c sides will form a straight line.

So we can say that another square is formed with side (a+b)

So, area of big square=area of 4 triangles + area of small square

$(a+b)^{2}=c^{2}+4*(ab/2)\\a^{2}+b^{2}+2ab=c^2+2ab\\So,a^2+b^2=c^2$
