Theorem | cevath 43003* |
Ceva's theorem. Let 𝐴𝐵𝐶 be a triangle and let points 𝐹,
𝐷 and 𝐸 lie on sides 𝐴𝐵, 𝐵𝐶, 𝐶𝐴
correspondingly. Suppose that cevians 𝐴𝐷, 𝐵𝐸 and 𝐶𝐹
intersect at one point 𝑂. Then triangle's sides are
partitioned
into segments and their lengths satisfy a certain identity. Here we
obtain a bit stronger version by using complex numbers themselves
instead of their absolute values.
The proof goes by applying cevathlem2 43002 three times and then using cevathlem1 43001 to multiply obtained identities and prove the theorem. In the theorem statement we are using function 𝐺 as a collinearity indicator. For justification of that use, see sigarcol 42998. This is Metamath 100 proof #61.
