Proposition: Prop. 9.02: Numbers whose Product is Square are Similar Plane Numbers

Euclid's Formulation

If two numbers make a square (number by) multiplying one another then they are similar plane numbers.

• Let $A$ and $B$ be two numbers, and let $A$ make the square (number) $C$ (by) multiplying $B$.
• I say that $A$ and $B$ are similar plane numbers.
