Book VI Proposition 23 | |
Since, then, it was proved that, as K is to L, so is the parallelogram AC to the parallelogram CH, and as L is to M, so is the parallelogram CH to the parallelogram CF, therfore, ex aequali, as K is to M, so is AC to to the parallelogram CF. But K has to M the ratio compounded of the ratios of the sides; therefore AC also has to CF the ratio compounded of the ratios of the sides. |
