I want to know what does the illustration from the text below looks like:
"Prop. 9. If two triangles have an angle of the one equal to an angle of the other, and the sides about another pair of angles equal, each to each, then the third angles are either equal or supplementary."
I just took it from a scanned book named "Elementary trigonometry" from the Internet Archives website, here's the link for the book: https://archive.org/details/elementarytrigon00paterich
Thanks if the answer was illustrated.
In the image above, say you started with triangle $ABC$, you know $\angle CAB$. You also know $AC$ and $BC$. If you start from the segment $AC=A'C'$, and the angle $CAB=\angle C'A'B'$, at the distance $C'B'=CB$ there are two points (see $B$ and $D$ in the figure. Is this explanation enough?
