I found this and everything makes sense.
But I don't understand how CPhill got to 2xh + 2yh = 2ab . I tried working out and expanding the given equation in the problem and using the triangle similarity he provided in an attempt to get what he got, but I don't understand how. Does anyone understand and can explain this part to me? Thank you!
+781 I asked for how CPhill got that expression...
Can anybody else help?
+23252 In the original post, there was this equation:
x2 + 2xh + h2 + y2 + 2yh + h2 = x2 + h2 + 2ab + y2 + h2
Subtract x2, h2, y2, and h2 from both sides and you are left with: 2xh + 2yn = 2ab
+781 Oh I see...I didn't see the OP's working. However, I don't understand how the equation leading back to h/a=b/(x+y) proves that (x+h)^2+(y+h)^2=(a+b)^2.
