    small to big is 1:2; since it's perp bisector, that's another 1:2. since small to big is 1:2, we have big/total, or 2/3, and since that's cut in half, 1/3

    i just thought that it's half an area of trapezoid so the ratio might be \(\frac{b_1 + b_2}{2}\) lol

    oh wait...my ratio should be \(\frac{b_1 + b_2}{2b}\) lol my ratio makes no sense
