Proposition: Prop. 10.108: Side of Remaining Area from Rational Area from which Medial Area Subtracted
(Proposition 108 from Book 10 of Euclid's “Elements”)
A medial (area) being subtracted from a rational (area), one of two irrational (straight lines) arise (as) the square root of the remaining area - either an apotome, or a minor (straight line).
* For let the medial (area) $BD$ have been subtracted from the rational (area) $BC$.
* I say that one of two irrational (straight lines) arise (as) the square root of the remaining (area), $EC$ - either an apotome, or a minor (straight line).
