Proposition: Prop. 10.100: Square on Minor Straight Line applied to Rational Straight Line

(Proposition 100 from Book 10 of Euclid's “Elements”)

The (square) on a minor (straight line), applied to a rational (straight line), produces a fourth apotome as breadth.

• Let $AB$ be a minor (straight line), and $CD$ a rational (straight line).
• And let $CE$, equal to the (square) on $AB$, have been applied to the rational (straight line) $CD$, producing $CF$ as breadth.
• I say that $CF$ is a fourth apotome.
