Commentary on Proposition III.29

Back to Proposition III.29.

[Folio 0067 | p. 61]

The particular case of this converse of III. 28 in which the given arcs are arcs of semicircles is even easier than the corresponding case of III. 28 itself.

The propositions III. 26—29 are of course equally true if the same circle is taken instead of two equal circles.
