Book VI Proposition 23 | |
Now since, as BC is to CG, so is the parallelogram AC to the parallelogram CH, [VI.1] while as BC is to CG, so is K to L, therefore also, as K is to L, so is AC to CH. [V.11] Again, since, as DC is to CE, so is the parallelogram CH to the parallelogram CF, [VI.1] while, as DC is to CE, so is L to M, therefore also, as L is to M, so is the parallelogram AC to the parallelogram CF. [V.11] |
