Question

how to prove c^2=a^2+b^2?

Answer 1

let's say we have a triangle
each side is length 3, 4 and 5cm

5 cm is the longest side
so lets draw this triangle

Answer 2

C= longest side
A= one of the other sides
B= one of the other sides

okay so

C²=A²+B²

5²=3²+4²
25=9+16
25=25

Answer 3

i think this would be enough to prove it... someone correct me if i am wrong
