# Math Help - pythagorean theorem

1. ## pythagorean theorem

My question :

Give another proof of the pythagorean theorem by using the equations : a/c = e/a and b/c = d/b obtained from similar trigangles in some figure. (the figure is a triangle with sides abc. there is a line down the middle making it into 2 right triangles. B and A are the hypotenuse's. c is split into 2 sides D and E making C = D+E)

Honestly I dont know where to start.

2. given data shows us that triangle with sides a,b,c is a right triangle.(because you've stated "similar triangles")

$a^2=ce$
$b^2=cd$
use these equations to show $a^2+b^2=c^2$
