Proposition: Prop. 10.091: Side of Area Contained by Rational Straight Line and First Apotome

(Proposition 91 from Book 10 of Euclid's “Elements”)

If an area is contained by a rational (straight line) and a first apotome then the square root of the area is an apotome.

• For let the area $AB$ have been contained by the rational (straight line) $AC$ and the first apotome $AD$.
• I say that the square root of area $AB$ is an apotome.
