Prove that a triangle is rectangular when:( x + y) / 17 = (y + z) / 18 = (z + x) / 25, (with x, y and z as the sides of the triangle).

How to ?

Find the values for x,y and z

I get for any constant

then show that

OK!

Thats the way to do it. I get the same results setting z = 1 and solve for the two unknows x and y (in function of z)

Never would have thought of this by myself.

Thanks Martingale.
